Frequently Asked Questions
What envelope size fits a 5x7 Mother's Day card?
A7 envelopes (5 1/4 x 7 1/4 in) are sized to comfortably fit 5x7 cards and small photos without bending. Choose a slightly larger booklet-style (6x9) if you include extra inserts.
Are peel-and-press seals secure enough for mailing?
Yes — peel-and-press or peel-and-seal adhesives are generally reliable for standard mail. For heavier or valuable items, pair the sealed envelope with a padded mailer or consider additional tape for extra security.
Should I choose paper envelopes or poly bubble mailers?
Use paper A7 envelopes for presentation (hand-delivered or first-class letters) and poly bubble mailers when you need protection from bending, moisture, or rough handling during shipping.
