Nice n shiny finish, good covering. Fantastic item, I use it all the time in all places and electronics.Item is listed as 40mm but when I received 2 meters of this 40mm heatshrink tubing, it was 65mm wide. It is too wide for my use and too much trouble/shipping to be RMAd. The rma process is to include in original package as received in, but my package consisted of a rather large box. It is not worth my time and effort to return this for an RMA. Just a heads up whoever is looking to get this, that the listed size is NOT CORRECT.buen termorretractil, muy fuerte y flexible calienteB E W A R E - its 65 mm - from EU warehouse !!!!
