Skinflex TPR is a durable, hypo-allergenic soft plastic free from phthalates*. Use water-based lube and wash with soap and water or toy cleaner. (*Phthalates (pronounced "thal-ates") are plastic softeners that are known to have carcinogenic properties. We do not recommend inserting them into the vagina or anus without a condom.)
These last longer than the typical stretchy ring. They'll still break but you can tell they're higher quality than most. They're also softer and I like the color options.
