If you plan on flying anywhere, TSA restricts the amount of liquids you can carry on a plane. Your liquids must be three ounces or smaller. Unfortunately, this means that your standard bottle of lube doesn't meet this restriction. Unique your wet fun by bringing along ID Lube - Jelly Extra Thick Water Based Lubricant 2 oz. This small bottle of lube meets TSA carry-on requirements and takes up only a small amount of space in your luggage, while still maximizing your fun.
