PerfecCut is very similar to 651 and is made with the same face film from the same company. PerfecCut comes from the American mfg of the company and 651 comes from the German mfg of the same company. PerfecCut has a different adhesive and liner. They are both glossy (although our PerfecCut does have a matte option for BLACK and WHITE). They both have a permanent, outdoor adhesive. They both have an up to 5 year outdoor life expectancy (3 for the Gold and Silver). If you haven't tried PerfecCut yet, try it today! Great for decals, signage, banners, window graphics, etc. Excellent cutting, weeding, and transferring and is made in the USA!
