Quality Park 10 x 13 Catalog Envelopes with Self Seal Closure, 28 lb Brown Kraft, Great Option for Mailing, Storage and Organizing, 100 per Box 44762

The Quality Park 10 x 13 Catalog Envelopes with Self Seal Closure, 28 lb Brown Kraft, has received mixed reviews from customers. Many have expressed dissatisfaction with the poor sealing quality of the envelopes, with multiple reports of the back seam coming undone and the flap peeling up on its own after a few hours. Some customers have resorted to using additional tape to ensure the envelopes stay sealed. There are also complaints of the envelopes being returned as undeliverable due to the unglued flap. However, it should be noted that each box contains 100 envelopes, which provides a decent quantity for mailing, storage, and organizing purposes.
