Things You Should Pay Attention to When Shopping for a Glass Butt Plug

Glass butt plugs need to be made a certain way and they need to have a specific design to be safe and to satisfy. If you don’t know how to choose such toys, here are the biggest essentials to pay attention to:

What kind of glass: Ok, just saying a sex toy is made of glass is pretty generic. What kind of glass is it? If you’re seeking top quality, choose borosilicate glass toys. Borosilicate is a special type of glass that is very much chip and shatter-resistant. As such, it will be much more long-lived than other kinds of glass. Borosilicate glass can also be heated up or cooled down rapidly. This characteristic makes it ideal for temperature play – one of the cool experiences that glass sex toys enable.

Be careful about coloration: Many glass sex toys look super beautiful because they’re colored or they feature swirls of various tones inside the glass itself. If you want a colorful item, make sure that it’s made of colorful glass. Glazing or paint added on top of the glass can be highly toxic (and there’s no way of knowing what the paint actually contains). This is why you should definitely seek items that are made of colored glass. It’s very easy to determine whether you’ve come across one or the other. Paints and glazes will often come off with rubbing and scrubbing. This is especially true for inferior products and cheap glass butt plugs.

Buds and textures: Some glass butt plugs are smooth, others will feature buds and protrusions for added stimulation. Be extra-careful when looking for such plugs. The buds on the surface should be expertly made. They still need to be smooth and edge-free. Poor manufacturing practices can result in edges and ridges that will be unpleasant and that could even cause some scratching or minor injuries.

Designed for anal use: Now that we’ve checked out the quality of the glass itself, let’s move on to the design of the toy. A glass butt plug should be created especially for anal play. It should have a tapered tip for easy insertion and a flared safety base. The flared base will keep the toy from getting sucked up inside the rectum (yes, that could happen!). If you get a glass plug stuck in your body, you’ll find it very difficult to remove the item without visiting the emergency room.

Length and girth: The dimensions of a glass butt plug should be chosen on the basis of your experience. If you’re just getting started with butt stuff, you should definitely go smaller. Narrow and streamlined toys will be easier to insert. At the same time, the heft of the glass will compensate for the smaller dimensions and give you a highly pleasurable sensation. Those who aren’t exactly sure what size makes the most sense should consider getting an anal training glass kit. Such sets consist of three or more butt plugs in different sizes. As such, the kits are really versatile and perfect for both beginners and some more experienced users.

Appearance: We’ve already discussed the fact that glass butt plugs look beautiful. If the appearance of sex toys is something that turns you on, pay attention to aesthetics. Some glass butt plugs can have bejeweled bases or a more fetish-y look to give you the visual pleasure you crave. While appearance shouldn’t be your primary consideration when looking for adult sex toys, do examine aesthetics after you’re done with more practical criteria.

Prioritize hand-blown glass toys: Is there really a difference between hand-blown anal toys and machine manufactured items. Yes, there is. Hand-blown glass items are made by experienced craftsmen who pay attention to all the details. As such, the quality is higher than in the case of machine mass-manufactured items. When a human isn’t paying attention, there’s always a risk of some defects. Hand-blown toys tend to be much more exquisite. Do keep in mind that they also happen to be a bit more expensive.

Suitable for prolonged wear: Anyone going through anal training may want to wear a glass butt plug for prolonged periods of time. In order to keep a toy for hours inside your body and feel comfortable, you have to choose the right design. Slimmer items with a narrow stem are typically best for prolonged use. Check the manufacturer recommendations before buying – there should be some information on the amount of time you can wear the specific glass butt plug safely.

Why Should You Buy a Good Glass Butt Plug

The question doesn’t just apply to glass butt plugs. It’s a valid concern as far as all sex toys go. There’s a reason why – the market is poorly regulated. As a result, you can easily end up with an item that’s poorly made, defective or even dangerous.

Glass sex toys are not created equal.

In the past, the term Pyrex (borosilicate) applied to a very specific kind of glass. It’s an American icon that originated in 1915 and that has been a quality staple since then. Unfortunately, things have changed and not for the better.

The original borosilicate glass recipe came in existence in 1908. The patent expired in 1936 and a new recipe was developed later on. It was still called Pyrex but it was different from the original.

As of 1998, all Pyrex items sold in the US are made of tempered soda-lime glass, a material that’s different and more fragile than the original. Today, many items sold under the Pyrex label aren’t as durable or shatterproof as originally advertised.

This is why you need to buy well-made, high quality borosilicate sex toys (and not just anything labeled as Pyrex glass).

Even if you go for standard glass, there’s very little risk of it breaking or chipping inside you. Handling and storage, however, could contribute to some damage. Hence, you should do your research, understand how glass products differ and seek out the original borosilicate that can give you complete protection against fracturing (even if you engage in temperature play often).

Apart from paying attention to the material, you also have to be careful about the design of your glass butt plugs.

From the reviews featured above, you’ve probably gathered already that three design elements are quite important – the tapered tip, the neck and the flared base. A tip that isn’t streamlined enough will make the butt plug difficult to get in. A neck that’s thick will result in retention challenges. And finally – a base that’s too narrow will contribute to potential health dangers.

So, it’s not just about aesthetics, pleasure and cuteness. Safety should be your number one consideration when buying sex toys. Poorly-made items cannot give you the safe, discomfort-free experience that we all crave from adult toys.

Don’t shy away from doing research and extensive sex toy comparisons. This way, you’ll gather enough data to make the best choices. High quality glass butt plugs don’t have to be expensive. Rather, the manufacturer should stick to some industry practices. Adhering to guidelines and manufacturing essentials will result in a high quality and safe item, regardless of the price tag.

Anal play is a lot of fun but it involves some personal responsibility before anything else. You need to prepare adequately and you need to invest in good toys. If you manage to meet both of these conditions, you’ll definitely have hundreds of exceptional experiences.

Final Words

Glass butt plugs give you access to a whole new world of erotic enjoyment. Don’t dismiss them, even if you’re somewhat reluctant about the material. Yes, glass is firm and completely inflexible. But that’s precisely where its incredible appeal is hidden.

A glass butt plug is the perfect, non-threatening item to start experimenting with.

And if you choose the right one, you’ll definitely be pleased.

Start out small and cautious. The market gives you many amazing choices for beginners. The fact that glass is solid and inflexible means that even a small toy will give you the kind of sensation you’ve never had before.

Hopefully, our guide has highlighted all of the important characteristics to pay attention to when buying. Glass toys may look misleadingly simple. Still, there’s room for error and manufacturing issues. By doing your research and focusing on quality, you’ll reduce the risk of getting an item that isn’t fun to use (or that’s dangerous).
