Knex Handcuffs
As you can see in the photos, these handcuffs are very easy to make and do not require a lot of pieces. They are also adjustable in size (you just have to add or take off some of the frames with the red corners) and are very sturdy. Once you are in them, you pretty much can’t get out.
Supplies
Uses very little pieces.
