This CHEWIGEM® is classic button disc shape, stylish and sophisticated for any young child or teen, but also quite neutral and suitable for males, especially if you cut the cord length. If you imagine putting your thumb into a dod of playdough, that is the shape, thicker at the edges and about 2 inches across. This is a robust chew suitable for more aggressive chewers.   DURABILITY - 3/3 FLEXIBILITY - 1/3 FIRMNESS - 3/3
