I had been searching for a time-lock safe for some time (so I could put handcuff/shackle/chastity keys in it for extended periods) but turns out they are REALLY hard to find, VERY expensive and most come from Europe.  The only other thing I have seen are the ice self-bondage locks from Mr. S but those have limited use and can’t be used for real long scenes.

After one exhaustive search I came across a time-lock small box safe that is made for people who want to stop their bad habits (like cigarettes, snack foods, etc).  I decided (for less than $100) I would buy one of their safes and it really is GREAT.  It is small enough to carry anywhere and can be kept IN a cell or cage with you (or just within reach) yet there is NO way to unlock it once it is set for a certain time period.  So far, I am very happy with it (of course NOTHING beats an actual CAPTOR carrying the keys to your bonds but they are often hard to find all the time).  One thing I do in addition for safety since I have to practice self bondage at times and live alone is I usually take my cellphone and put it within reach of my cuffed hands outside the cell/cage so that IF the safe did not open for some reason or I needed emergency medical help I could call someone.  Of course calling anyone would be VERY embarrassing and you would only do it IF you were in real jeopardy…otherwise you are forced to wait until the safe opens at the specified time.

Although the safe comes with 2 regular keys to use as well they do NOT send you these unless you ask for them and if you DO ask for the keys they allow you to send them back to them for safekeeping as a free service for their customers … in order to avoid anyone opening the safe prematurely.

Oddly enough, the name of this company is Captured Discipline. They list many many uses of their products (EXCEPT this) You have to wonder if they sell many of these to us twisted bondage addicts. I am also curious if anyone else has seen/purchased this product.
