Visible Cutaway Handcuff
This visible cutaway handcuff is similar to the cutaway practice padlock, but instead of using a transparent interface to teach you how to pick a padlock, it uses a transparent interface to teach you how to pick a pair of handcuffs. Aren't you glad I'm here to explain the mysteries of life?
The see-through single cuff from SouthOrd also comes with a set of keys in case your training doesn't go so well. Lock picking tools are not included, but the cuff does allow for both single-lock or double-lock picking.
