PRINTFILE 45-4B Pol, 100 sheets, for 4x 10.2 x 12.7 cm

File sleeves made of uncoated, pure polypropylene and polyethylene. These high-quality sleeves are a reliable alternative to the widely used, non-archival-grade glassine and acetate sleeves. The polypropylene version is sturdier and clearer than the polyethylene version. Contact prints can be made directly using all of these sleeves. Some of the sleeves are also suitable for hanging rails. Top opening
