D-Line Beading (Horwich BL6)

This D-line beading can go into corners and hide a cable. It's been in the garage for a while as it was surplus to requirements but I thought a use would come for it but would now prefer to give it to someone who can use it. There are 4 unopened packs, all 2m long. The blue area is the sticky part that attaches to your wall/floor etc. You can just about see from the photos that it opens to allow whatever is to be hidden to go inside and then close up again with a snap. It says it's 16 x 8mm.
