Keep-O, the Toys for permanent stretching
The Keep-O Buttplugs are another innovation from Organotoy. Their main purpose is to keep your back door as open as possible. Keep-O stands for Keep Open.
The Keep-O´s are designed so that the strain diameter is as close as possible to the largest diameter (the diameter of the head), but still holds well (if it has a size close to your largest used toy). The long foot adapts to your bottom like a glove.
The Keep-O 75 has a maximum diameter of 2,95 inch and a shaft diameter of 2,56 inch, the undercut (the constriction) directly behind the head is slightly smaller. The total height is ca. 4,61 inch.
