The industrial-strength adhesive present in the genuine Dymo 18508 cartridge makes its black on clear labels stick to most surfaces, even those that are highly textured. Once the 9mm labels produced with the Dymo S0718160 have been applied, they can resist moisture, high temperatures and UV light, all without loosing their adhesion.The 5.5m of thermal label you get in this original Dymo S0718160 label cartridge cannot smudge, smear or fade, so results of your printing will be present for the foreseeable future. Dymo have even made sure that prints from the 18508 are easy to apply, thanks to the split back design that makes them simple to handle, even in trying circumstances.
