Are vibrating sex toys on the way out?

One of my favourite sex toys looks like a slice of jelly. It’s a psychedelic shade of bright green and shaped like a tiny rectangle and has a slippery silicone texture. It also requires zero batteries or power at all. It sounds simple, but it’s the simplicity of the TENGA Uni toy that I love so much. Able to slip over fingers or a penis (or whatever else you fancy) and usable by yourself or with partners, each colour of this toy provides a different barrier of texture, giving that contact a little something extra.
