A: Our Small Sleeve fits the Standard (small) NMJL card (4″x 5 1/8″) ONLY. (It does not fit the small Siamese Mah Jongg® League card.)
Our Large Sleeve fits the Large NMJL card and the Large Siamese Mah Jongg® League card which are different in size. Each requires its own custom fit Sleeve.
All of these cards need covers, the Siamese Mah Jongg® League cards in particular. They are made of slightly thinner stock paper. It is a great card though and should be covered to preserve it for frequent use! 🙂
