works well. Useful for storing paper files just add title on envelope and place in file cabinet. useful for tax files music files special memos records to keep and the manilla folders fit into these envelopes so the folders of like kinds can be combined into one envelope.
This envelope might work great for mailing 8 1/2 x 11 document but for mailing t-shirts we found that the peel and stick tab needed extra pressure to be secured.
