## Description

desertcart.com : 6x9 Booklet Envelopes - 250 Pack - Self Seal Mailing Envelopes - White Letter With Peel & Seal Closure - Open-Side - 28 Lb Paper - Plain for Business and Personal Use : Office Products

Review: Quality and Ease! - Nice and opaque. The self-seal strip is a game changer!
Review: Used for several years now for Christmas cards - Review actually applies to previous purchase. I try to replenish stock after use, and so a box of envelopes purchased in December probably is mostly used for the next year's Christmas cards. (We have been printing our own on 65# cardstock for a number of years.) Folded in half, as cards are, this 8.5x11 stock fits nicely in these envelopes, along with a letter, and fulfills Post Office requirements of dimension and weight for a single stamp. Compared to previous supplier's envelopes (Staples), these are slightly better. They feed reliably through an H-P 8600 printer with nearly no issues (1-2 misfeeds a year at most) when printed 20 at a crack, and retain their self-sealing ability even after being on the shelf for a year or more. They are boxed properly to arrive in good order for easy use. They take ink well. Allow adequate margins, but that's not hard on an envelope this large. Our annual usage for Christmas is approximately 215, and we use a few through the year for other mailing, typically to avoid excessive folding. They are good carrier envelopes for these cards we sometimes use for condolence letters: https://www.desertcart.com/gp/product/B004O77NVE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 If we include an envelope bearing cash, we will see the need for extra postage, but the fact of the cash will be undetectable, and, so far, these have arrived reliably when so used. The carrier envelope makes the purpose of the communication opaque.
