Better than what I thought

The product is even better than what I expected: I had relied on the weight to estimate the number of envelopes which was not indicated, a flash estimate gives me about 1000 envelopes.
The quality is excellent, I have written in pen without it catches the paper and the ink has dried without any burrs. The gummed adhesive holds very well.
No external printing envelopes (no PO pre-printing on the front), no marks on the back, which I appreciated. Grayed tint inside.
