Bought these envelopes at a good price but they are not sturdy. The paper weight is very light and flimsy. Several envelopes in the box were creased and had failed side seams. I will eventually use these but don't feel confident using for important mail.
Used these envelopes to mainly send business letters (1-3 pages each). CON * Very thin and flimsy... had a hard time running them through printers when printing address info--they were too flimsy for the printers to grab correctly (if at all). If you are going to be feeding envelopes through a printer you may want a better quality / sturdier envelope. PRO * Easy to seal
I hate licking envelopes to seal them! No more paper cuts on my tongue! With the security tint I no longer need to waste a blank sheet of paper to shield enclosed checks! My tongue thanks me every time I use one.
