My solution:




Still too early to say if it will work as good as I hope, though... But I am optimistic.


It is plain and simple a piece of PET plastic (cut-out from a bottle of Heinz' tomato ketchup, they have these nice corners that forms the sharpest bend) and a bit of gorilla (duct) tape.

If you leave the PET piece just a little too short to go all the way around the BIC you have a permanent storage solution. If you make it a bit longer you've made yourself a low bulk BIC case. If you like to tie it to other things then you just insert a piece of line when you wrap it with tape.
