Tenga Love Egg. A twisting series of intense ridges make for a wild ride! One Size fits all. While it is recommended the Eggs be used only once and disposed of, if they are properly used and cared for they can actually be used multiple times! The first step is to use the Tenga Egg Lotion designed specifically for the longevity of the Egg and also your pleasure, of course. After use, rinse the egg thoroughly inside and out with warm water and a very small amount of gentle soap. Air dry. More details on using your Egg Multiple times here.
