It is the same issue on the Love Pacifier things too. They are listed as TPR but the packaging says 100% silicone. The vinyl vengenace is super confusing because it lists 2 material on the package, TPR and sil-a-gel. I guess the exterior is TRP and it is sil-a-gel filled. Another one that has 2 materials is the rippled purple passion that is jelly or sil-a-gel filled too. The radiant gems items are sil-a-gel, but my crystal jellies packaging says jelly. I have the double dong and an anal probe thing I think from that line. The materials I find can be confusing.
