#10 Security Self Seal Envelopes – 100 Qty |No Window, EnveGuard, 4⅛ x 9½", White, 24 LB, 100 Count (34100)

These security self‑seal envelopes have become my go‑to — and yes, I’ve bought them a few times now. They’re nice and thick, so nothing shows through, and the self‑seal feature is a lifesaver for anyone who refuses to lick envelopes like it’s 1995. The pricing is totally fair too, especially for the quality. If you want envelopes that feel like they’re guarding state secrets but don’t cost a fortune, these get the job done with zero fuss. A must buy.

The 100-pack is just the right size for my stationary drawer. The security feature is perfect for me, and because it is self-sealing, I don't have to worry about the humidity sealing all my envelopes before I can use them. The price is good and since I have it on subscription, I get to save a little bit more. Also, I think these envelopes are good quality.

Good quality envelopes. Paper is strong without being too thick and a decent shade of white. Went through the printer with no jams or issues.

I love these envelopes. They are high quality and beautiful. The adhesive is excellent. Very pleased with this product and plan to use them going forward.

Very well made, secure for sure, but I think a bit overpriced.

Simple envelopes that are good quality. I like the self seal ability of these. You don’t have to attempt to lick them. After the envelopes get old (not long) the envelopes don’t seal completely and this avoids that problem.

Good sturdy strong envelopes

Great envelopes with quality adhesive. The security of each provide extra protection.

Well overpriced envelopes, feel similar to much cheaper PPS envelopes in officeworks.
