Vibrators made from jelly are most often soft, flexible and colorful. Jelly has an advantage over other materials in that it is very easy to mold, color and shape into whatever the sex toy designer can imagine. As a result, there are a wide variety of colorful, beautifully crafted jelly vibrators to choose from. Jelly is also a very pliable material, which contributes to a soft, smooth and supple feel that is unique to jelly vibrators.
