This acid-free tissue paper is great for protecting invitations and photos when mailing them in an envelope. Some types of printing can rub off during mailing, ruining the finish on the item and transferring ink onto other items in the envelope. This tissue can help with that and add a touch of elegance at the same time. 100 sheets per pack. Made in USA. We can custom-cut this tissue for you - just select Custom and specify the size (must be between (2in x 2in) and (8in x 10in).
