Material

There are two common types of plastic used for sex toys, PC and ABS. They are both a hard material often used for many sex toys, because plastic is inexpensive, body-safe and hypoallergenic. Plastic is a non-toxic, non-allergenic, non-porous material that is unscented, phthalates-free and latex-free. Plastic may seem like it has a smell when the package is opened, but removing from the box and washing it takes care of it.

Since the material is hard, the vibrations travel really well along the toy if it’s a vibrator, meaning that you will apparently get more power from the same batteries if your toy is made of plastic than silicone for instance.

Toys made of plastic are sometimes coated with a layer of polyurethane, PU, to make the surface velvety and give it a nice texture. Polyurethane is also a type of plastic and shares the same characteristics.

Care

Plastic can easily be washed with a mild antibacterial soap and water, or with an antibacterial toy cleaner.
Even if plastic is non-porous and can be technically sanitized with a 10% bleach solution or with isopropyl alcohol, plastic toys may have seams that may make it hard to completely sanitize. So use your judgment and, if you have any doubts, and that you want to share your toy, a condom is recommended.

It can be used with any type of lubricant, meaning silicone-based, water-based and even oil-based lubricants.
As with any sex toys, remember to wash your toy before and after each use.

Storage

Plastic toys do not have special requirements when it comes to storing them next to other materials. Still, I believe that any toy should have its own bag to prevent any accidental scratches on the surface.

Most of those toys are vibrating and as such require to be stored in a dry place as to not damage the mechanism. Remember to remove the batteries from any vibrator during storage as well.
