finger vibrator

Most finger vibrators are rechargeable lithium‑ion devices and include USB or magnetic USB charging cables. At least one listing describes a non‑battery manual toy made from TPR and labeled as having no battery.

Most listings specify silicone (with some stating medical‑grade silicone); one product lists TPR (thermoplastic rubber). Many descriptions also advertise phthalate‑free, hypoallergenic, BPA‑free and latex‑free materials, and some explicitly note they are free of parabens and phthalates.

Many descriptions state the products are waterproof or fully waterproof and can be used in the bath or shower; common phrases in listings include "100% waterproof" and "fully waterproof."
