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 100 has a maximum diameter of 3,94 inch and a shaft diameter of 3,54 inch, the undercut (the constriction) directly behind the head is slightly smaller. The total height is ca. ... inch.
