Each of these envelopes has required to be tape added to seal the right side of the envelope. I would not recommend them dreadful quality as far as security. Is there any quality control checks at Staples? Not with these envelopes.
Great product if you can get it for a good price. The seal is durable and strong. The paper material is not the toughest but it's good for most uses. The security feature works quite well. You can hardly see inside.
This beats licking or using wet sponges to seal monthly billings for our business; really saves time. A big plus was the coupon you recently gave for 70% off. The envelopes are a little pricey so that really helped!
Staples #10 Standard Size Envelopes are Security Tinted with a QuickStrip seal. No worry the envelopes lack padding as they are for everyday mailing of important content documents.
