I have green, yellow, brown and orange.
No stamping on the green, brown and yellow.
My orange has the SSMC rubber overstamping.
Did I mention the orange like the green is not listed on the Mason Cards?
Anyone have the red, blue, and lavendar ones to trade?
OR any other color in the rainbow not listed on the cards??????
Overstamp is light but its there. Look for the SS on top left of the M.
