The bags that SSA Glass toys come in are red velvet. It's a very thin material and not padded at all. On most of mine only the outside is the furry velvet, while the inside is just the plain back of the material.
While it is a small toy, for me personally it is just perfect size-wise. I think for this kind of pin-pointed G-spot stimulation its the design that works for me and not really a function of the size. It's the curve that does the trick for me - BIG TIME!
As a point of comparison to my general size preferences in toys, my favorite "everyday" dildo is the VixSkin Goodfella.
The Amethyst gives a totally different experience. I find the Goodfella mimics the feeling of penetrative sex. while the Amethyst does not - it just really stimulates my G-spot perfectly. So depending on what I want, both are awesome toys!
If I were only allowed to keep 1 glass dildo and 1 silicone dildo, those would be my 2 choices - hands down!
