I fucking _love_ anything 'tamper evident'. These are the keys for my wrist cuff and some plastic tubing from Lowe's (left over from another project >.>)
Chastity keysafe on a budget:
A travel toothbrush kit - https://www.amazon.com/Dental-Source-Toothbrush-Toothpaste-Assorted/dp/B0079MRKVE/ref=sr_1_38?crid=2AC7YDBIIMRBO&keywords=travel+toothbrush&qid=1576618558&sprefix=travel+tooth%2Caps%2C152&sr=8-38
and some tamper-evident tags - https://www.amazon.com/gp/product/B0746P7349/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
Drill one hole through the pink part of the toothbrush case, string your keys on the arm of the tags and voila. Accountability!
