The product itself is nothing to complain about, except that it is way overpriced. It is here to strip pieces that are glued to a A2 paper and piece by piece with tact must be glued to the rim (one has times a 20-30cm long, curved strip pieces in hand, it is guaranteed bulge / stick / not properly seated on the rim). If you do not have finger-surgeons, the precision work is frustrating, the transitions between the pieces I do not get and therefore chucked the whole thing in the trash. For a few Euros LESS I got me a lot of the merchants higher quality coil with adhesive auxiliary Dings-Bums bought and voila - a thousand times easier, looks clean, easy to stick. My recommendation - do not buy!
