I’ve been buying the extra TS/nosepads that came with the boxes when available so I have 3 extras plus the one from my complete set which I plan on keeping
1) I know I have one TS15 for sure never mounted.
2) I have another ts 15 set I stupidly threw into a partial set that I striped from a display pair. To complete a full set. I don’t remember now which one was mounted and which one I bought new.
3) I have one that was mounted and used.
