[Set of 50]
[400 pieces set]
The beautiful white color is made of cardstock so it is more durable than standard envelopes. Comes with double sided tape to seal and no additional tape or glue required. It also comes with an open zipper (opening tape) for convenient opening. These envelopes are very convenient for shipping booklets, books, papers and more. Shipping is possible by Mail-bin or by courier. Please note: The listed size is the flat size without any insert. When inserting the contents, the thickness of the contents will expand and therefore the size will be narrow, so please check the thickness of the contents before using. The perfect size and large sizes may not fit depending on the item, so please choose a size with a margin of room. If you want to store thick A4 paper size, we recommend a tall cardboard box or a little larger cardboard envelope. There may be an inevitable error of ± 0.1 inch (3 mm) during the manufacturing process. Please acknowledge
