Review on 40 #10 Security Tinted Self-Seal Envelopes - No Window, 24 LB White EnveGuard Size 4-1/8 X 9-1/2 Inches - 40 Count (34140) by Esera Warren

If you need a good business envelope, this is it! They are tinted inside for great secure writing! No one can see what's inside! And they are peel and stick openings! No licking or sponging EVER! And the price for all of this is so close to what you pay for those flimsy, see through regular opening envelopes, in some cases cheaper then those other envelopes! Buy these envelopes! You won't regret it! I will have my supply of business envelopes, forever! I will buy nothing else! And the delivery is very fast! Even if it says in 2 days, I got them the next day! And I needed them fast, and that's what I got! No driving to the store and shopping, then driving home again! You order it on my phone, in my case or your computer, in the comfort of your own place! Then when I opened my door to attend my cats. They were on my doorstep, ready to use! They are perfect!
