Tall, Dark and Handsome

The Cobalt Bubble Plug is one that will be amazing for those that love glass back door toys. It's a bit large for a first time with glass, but it is one that I would recommend for those that have enjoyed glass anal toys before. The bubble makes for a bit of added sensation during insertion and removal, but it doesn't impede wearing it. This is a very pretty and functional toy for the glass lover.

extremely useful review


The Cobalt Bubble Plug from Don Wands is a great plug for intermediate to advanced users. Its size a weight will make it a challenge for beginners to anal play or glass anal toys.

It is safe for anal play because it has a nice neck and base to prevent it from being pulled into the body. It can be used for vaginal insertion as well; just make sure that the toy is fully sterilized.

This toy is larger and rigid, so it needs to be used with care to bruise anything. That being said, the rigidness of this is part of what makes it a great toy.

Material / Texture

This is made of glass which is smooth and has a bit of weight to it. I like toys that have a bit of weight to them because I find that they are more noticeable during wear, but not everyone will feel the same as I do about it. This toy is rigid, so be careful with thrusting not to bruise anything.

The Cobalt Bubble has no texture aside from the bubble above the neck which is a must have for me with anal toys. I hate texture on my back door toys. The gradual shape makes it really comfortable during insertion.

Glass has no odor or taste, nor does it hold on to any because it isn't porous.

Glass can be used with temperature play. This can be warmed in hot water or cooled in ice water 15 minutes before use to add new sensations.
    • Not porous at all
    • Rigid
    • Smooth

Design / Shape / Size

I don't normally purchase anal toys that have bubbles or bumps, but I got this one on a whim and loved it. The top portion is the gradual cone shape that I love. It then narrows to a section which then flares out into the bubble. The bubble is basically the same as the largest part of the cone, so it isn't any more challenging.

The plug is 5" in total length with 4.5" being insertable. At the widest, it is 5" in circumference. It's a challenge, but the smooth glass and gradual shape makes it less so. I still would only recommend this for intermediate to advanced users.


This is pure glass, so there are no vibrations, but glass can be warmed or cooled in water which makes it all kinds of fun. I personally don't like cold in my back door, but it's nice to be able to warm it up. You can use this anywhere as well.

I love the rigidness and weight. Glass offers both, and I adore it.

The shape was something a little bit new for me, but I loved it. I found that the bubble was pleasant because it wasn't any wider then the largest part of the cone, so it was just more of the fun sensations during insertion.

This was a bit heavy to retain during sex while I was on top, but that's because gravity wasn't my friend. On bottom or doggy style, this worked perfectly.
    • Comfortable
    • Easy to use

Care and Maintenance

Glass is an amazing product when it comes to care and maintenance. It is compatible with any lube or mild cleanser including toy cleaners and you can sterilize it by boiling it, putting it on the top rack of a dishwasher, or by wiping it with a 10% bleach solution. You can also wash it with and mild soap or toy cleaner and warm water.

I would recommend storing this in a location where it won't fall on to the floor. It is hard to break glass toys but not entirely impossible. A fall onto a hard surface too often may just do it.
    • Easy to clean
    • Easy to store


I am always blown away (haha! glass pun) with Don Wands packaging for the price of their toys. It's always sturdy and well designed while still being easy to open. The box isn't plastered with naked people, but it does have tips on how to use the toy with hot and cold, so it's not discreet if you can read it. Inside the box, the toy rests in a plastic tray that is cut to fit it perfectly.

I often just store my toys in the packaging until I can get a padded pouch for them.
Follow-up commentary
This has been a great addition to my collection. It is a challenge, but not pushing me too far. I love the solid weight of it when it is inserted.
