08-03-2026I had many bills/receipts etc. that i needed to organize and finally decided to get to it. I chose these envelopes for the quantity and the price. They arrived the next day and were exactly as advertised. They are not flimsy and the price is better than in some brick and mortar store that I would have had to go to the store and pick up. When needed I will buy this product again.

08-03-2026why do socks, and pillow cass disappear?I have very nice sheets sets but at times I can't find the pillow cases even though I wash them with the sheets. Thought I'd be throughtful and keep a couple spares around. these was just what I was looking for. Nice quality, reasonable price, now if the "dryer monster" snatches a pillow case, i have a couple of spares!!

08-03-2026Perfect size to mail business documents. Lightweight, as to not increase the weight of the mailing. You can also put in quite a few pages in the envelope. Easy to seal. Will purchase again,
