When I first saw that the little rubber grommets were just unattached, I engineered a complex and expensive capture system. LOL
1/2 size altoids tin.
Another possibility I’ve considered is drilling a small hole in the tab of each, and running a thick thread through each so that they stay together.
I tried to attach a photo but I can see it was too big to display. I ended up just Cable-Tying a ziplock snack bag to the handle to pop everything in. I just think it would have been good to have them captive so they don’t get lost.
