My mailer boxes are more beautiful than I could’ve ever imagined! Vistaprint did such a wonderful job with printing my more complex designs on my box. I can’t wait to send these off to my subscribers!

Took longer than some things I've ordered from Vista Print but the quality did not disappoint. A really elevated look to my snail mail packages for my clients.

Everything was fine but the top was a little blurry. Idk why these boxes could’ve shipped in on big boxes unfolded to save on shipping but I do appreciate not having to make the box
