Plain white envelope included.

Card measures 5.5" x 8.5" folded
Comes with plain white envelope (slightly bigger than card - size A9)
Printed on matte white card stock
Front = yellow ink
Inside = black ink
Back = colored ink
Optional: The card can come enclosed in a clear poly sleeve - leave message "POLY" in "Notes to Seller" if you want it so.
