A set of vibrating anal balls from Doc Johnson. They had sharp seams that needed to be sanded, and then the cord pulled apart, because the electric cord was meant to double as the retrieval cord. They've long since been discontinued, fortunately.
The Butterfly Kiss. I cannot, for the life of me, understand why anyone likes that toy. It is so weak, that all it did was frustrate me. The bullet part is near the base, and the rest of the toy is made of that awful TPR material, which just does not carry vibrations worth a damn. The insertable part is too small and sits too shallow for g-spot stimulation, your clit has to be insanely sensitive to get anything out of the butterfly part. I peeled all the TPR off and exposed the bullet underneath, and then it became an okay bullet, but I haven't used since I got my Enchanted Crystals bullet, which is much more attractive, better made, and stronger, even if it isn't the strongest vibe on the market.
