Card is approximately 4 x 5.25 inches and is printed on sturdy matte photo paper. The inside is blank. Variations include 'You are the Bert to my Ernie' and 'You are the Ernie to my Bert', and can be combined with either a white, gummed envelope (sustainable option) or a kraft self seal envelope. Card and envelope can also be packaged in clear plastic cellophane or you can choose the unpackaged option. All cards are manually printed and cut, so the sizing can slightly vary.
