PRINZ-SYSTEM, double-sided, 7 hole punching

Prinz-System is synonymous with stock sheets and is the result of long and intensive product development. Prinz-System stock sheets in the format 215 x 280 mm are made from pH-neutral card and covered with plasticiser-free and acid-free polyester strips (100 μm). These do not contain any harmful chemicals. The extra-strong clamping force of the polyester strips ensures that stamps or other documents do not slip. In addition, the stamps are completely covered by the foil, so that a cover for further protection is not necessary. Storage for decades has been proven to be safe.
