In that sense, I'd like to recycle some text and refer to one post I made at a different thread: https://unwedchastity.org/d/657-thighbands-with-padlock/155 .
If you don't want to fight through my notoriously long, pseudo-intellectual babble ;-) - although parts of me suggest you do, ofc 😄 - I can give the extreme conclusion: Ordering d-rings / connection points for accessories is a chastity-wise preparation just in case, and an economically sound decision.
And I should add: As always, but particularly in this case (to everyone who has the chance!): Choose your keyholders with care!
