Transparent protective sheets for postcards, letters and banknotes, made from a special fi lm that is free from chemical softener. The sheets are sealed on three sides, leaving the narrow side open (the banknote sheets are open on the top longer edge). Due to the thin, soft, non-tear fi lm, the sheets are very thin, robust and easy to use. Material: durable and sturdy PVC or polypropylene (see table). Packs of 50 or 200.
