We are making handmade shower invitations using a cricut for the design & these envelopes work perfect for mailing a large quantity. I am glad we do not need to lick all of the invitations. The envelopes are also a convenient place to store all of the die cut pieces as I am cutting that pieces that will be glued on to each of the cards. Trying to keep track of 9 different pieces that need to be glued on to each card would be difficult without being able to keep them organized in the envelopes as I go.
