This 4 5/8 x 5 3/4 inch clear flap seal envelope is ideally suited to fit a 5.5 Baronial or A2 envelope and greeting card. In addition, this bag works well to package stationery, postcards, notepads, crafts, and marketing mailers. The bag features a 1.6 mil USPS approved poly barrier to protect your cards, a resealable adhesive strip on the flap of the bag to create a secure seal, and a crystal clear material to ensure it's the card your customer focuses on, not the packaging. This sleeve is also available in our premium material for added protection and our Eco line for a greener solution. Please check the size of your product before ordering, and ensure that your product is smaller than the dimensions of this bag.
