A shackle is a standard restraint that binds both ankles.
The size can be freely adjusted with Velcro and restraint is easy. It fits perfectly regardless of physique.
Customization combining parts is also possible.
If you combine it with the separately sold <Teaseki>, the degree of restraint will be further increased.

The attachment and detachment of parts is one-touch with a connecting buckle. Even inexperienced people just pose and snap.
It is highly expandable, and you can broaden the range of play by combining <hand grab> <foot grab> <M-shaped spread leg> or combining it with the cross belt of <neck & hand grab>.

The texture is very soft because it is synthetic leather. The luxurious purple fabric material and plenty of cushioning are used on the inside that touches the bare skin, making it extremely comfortable to wear.
Easy to clean, even if it gets wet or dirty, just wipe it off.
