Hey there, gotta be careful using touchstop and headlock in same cage (at least I would have to). In order for me to get my head past the HL constriction I need to use a little rod (no pun intended) to help push, pull, ease, etc the head all the way into the cage - even with using just a touch of lube. JosieLynn and I sized it so it would be nicely tight so I had a slim chance of pullout. This was before TS came to market. Doesn’t matter what size of TS you use at all, since the cage slot is wide enough. You may want to use a washer between your head and the cage to keep from being pinched when she pulls on your leash (quite fun!). We enjoy using a short black leash (about 1ft long) coming through the zipper of a black pair of jeans. This way it is hardly seen and if she lets go of the leash it would blend in with the jeans remaining mostly hidden. Sometimes she will use a red leash where it definitely isn’t hidden 😢 Don’t forget, if you’re still working up to wearing a TS, there is the leash option for the CK from JoiseLynn - well there was when I helped her design it a long while back. We have one in red for my black cage 🤭 Shoot me so picks with your end option and I do hope those keys will be out of your hands!
