Great purchase. We use at work for sending off invoices and it does everything we need it too. Based on other reviews, I was actually surprised by its quality. Great product, will happily buy again

Just what I needed for my invoices. Sticky peel is a tad harder to peel off. Overall, I'm happy

The first box I ordered were great quality, thick, good privacy tint. So I reordered again. I'm part way thru this box, and now every envelope I try to use is defective. It appears as if the edges were not glued in the manufacturing process. Before now, I would have given a 5 star review. But considering most of my box is unusable, it's definitely a zero star!
