Blue Geometric Pattern Custom Return Address Envelope

This blue patterned envelope is printed inside and out with a modern kaleidoscope print and has a customizable return address printed on the outer flap on the back. The front has a plain blue area to write the recipient's address on. Use these to send fun pen pal letters, thank you notes, or party invitations. The inner design is an unexpected embellishment that will be visible when people open the envelope but not before, so it's a nice surprise for the person who opens it.
