Hello, suction cup! We've been looking for a toy with a true, functional suction cup base, one that will stand up (ahem) to a little vigorous action. The Colours dills definitely fit the bill.

These are silicone, dense, and very realistic in shape, right down to the balls. The design also features a shaft that's slightly wider toward the top, and veiny details which offer some intense texture. These are mass-manufactured dills, and you won't find the fine finishing or velvety texture that are the signature of the top-end manufacturers. But you will find a sturdy, inexpensive toy with enough suction to take anything you throw at it. Well, almost anything.
