ValBox 9x12 Self Seal Catalog Envelopes 250 Packs White Envelopes with Peel and Seal Flap for Mailing, Organizing and Storage

They are good envelopes and sturdy.

I have purchased these envelopes about 10 or so times. The price per unit for the quality of the product is about as good as you’ll get at just 250 pieces. The paper thickness and adhesive is always strong and dependable (if you seal it and realize you forgot to put something in, just use a new one because the adhesive is strong and you’ll rip the paper trying to open it without heating it first). I typically use them for shipping patches, single ones inside folded paper or multiple in a ziplock bag and never have quality issues. Two orders I got varied in a lesser quality than usual, but even then they were still dependable. Sometimes there’s variances in manufacturing process or manufacturers in general but seems as they responded to the feedbacks and went back to the initial quality. Shipped in a very sturdy cardboard box that never has arrived damaged even when shipped in only the product box itself. Buy with confidence.

Excellent value. And a good product. I will be buying my envelopes from you absolutely.

Great buy!

Good value

Well built envelope. Size is good. Paper is good, although maybe not quite as sturdy as some other brands. Flap adhesion is very good and properly applied, although the glue is set back from the edge of the flap. I personally would like to see the adhesive applied closer to the edge of the flap. Are these worth the extra price....probably.

great product at a great price.

These are good envelopes and can be sent with one stamp in usps.

cheap and efficient.

Needed something a bit stiffer, so didn't really meet my needs.
