Greetings, people behind the Kink!
I'd like to know how you fix your magic wands to take all the squirting, lube etc they are subjected to in your shoots? Maybe give us a tutorial? I have a good old metal headed Hitachi wand that I can get cheap replacement heads for from China for few bucks but I'd feel more safe and secure if it was properly sealed like the ones in your shoots.
I've figured out it's quite ok to take off the cap and clean it all with water and soap as long as I don't let water inside the thing and then letting it dry properly. No issues so far after years of use. However it'd be so much easier to clean if I didn't have to do that.
We also have a bunch of attachments but they are only as long as the cap and don't protect the joint or the inside of the head very well.
