My hubby bought a pack of these envelopes, Paperline Plain Envelopes, when he needed many for distributing funds for his workers. This envelope he chose actually is not really a perfect size for putting banknotes in it. He had to fold the banknotes to be put in it. He was in a rush at that time, and the envelopes he used to buy had been out of stock, so he had no other option. This envelope has the booklet size of 95 mm x 152 mm (see, it’s quite small for banknotes) and 80 grams in each weight. A pack of these contains 100 pieces but the best part of it is that each envelope has a ‘peel and seal with security cuts’ feature. It has some kind of seal that must be peeled to seal it, so we shouldn’t bother to seal it manually with glue. The seal seals the envelope just all right, makes it very easy to open. 80 grams makes it quite thick for an envelope, and this is a good thing. Overall, my hubby seems satisfied with this envelope, although he definitely needs ones that are bigger than this.
