These are, as the headline suggests the larger Glass Dildos out of our collection. Keep in mind that Glass is different from other materials used for Dildos. In this case it is important to remember that glass is very dense. While the pieces themselves are not 'stupid big', they are very heavy, thus the feeling with penetration is that they are MUCH bigger than they really are. A small Glass Dildo feels bigger than it really is, while one of these larger ones actually feels huuuge.
