Feeds better to my inkjet printer if I squeeze the edges of a stack of envelopes first. I print my logo on these envelopes to deliver photographs and cards. Matte photo quality results.
I send out many homemade greeting cards which are important to me. These envelopes are of the highest quality (They will get thru the Post Office machinery intact) yet couldn't be easier to use. In addition they have a 'good look' to them.
