Frequently Asked Questions

Q: How did you come up with the idea of Mah Jongg Highlighters? 

A: That’s a great question and a lovely story. Read about it here, in MY BLOG.


Q: Can I place the Highlighters on my old card protector?

A: Yes. Our Mah Jongg Highlighters work fine on them. Those card protectors seem to cloud and crack quickly so that's why we love our card Sleeves and recommend using them with our Highlighters.


Q: Can I use the Highlighters directly on my Mah Jongg cards without your Sleeve?

A: Use the Highlighters with our protective Sleeve or another card cover. If used directly on your Mah Jongg cards, the Highlighters will get dusty and lose their adhesive properties. We guarantee that they work best with our clear, protective card Sleeves.

Q:  My Highlighters are getting dusty and seem less sticky. Can I wash them?

A:  Yes! Washing them will make them sticky again. Spray them with Windex and rinse with warm water. Or use a drop of "the Blue" degreasing dish soap on either side of the Highlighter, rub and rinse with warm water. Gently pat dry with a lint free rag. They will be like new! Watch this video on Washing your Mah Jongg Highlighters.

Q:  How do I store my Highlighters between uses?

A:  Leave them FLAT on your protective card Sleeve and tri fold closed. Make sure the Highlighters are kept away from the creases of your card when tri folded closed. A crease in your Mah Jongg Highlighter will diminish its adhesion properties. Keep them FLAT.

Q: Will your Sleeves protect my card from liquids?

A: Yes. Our uniquely designed card Sleeves have a 1" flap on one end and an adjustable velcro dot to completely enclose and custom fit the card you want to protect. It's water resistant.

Q: What Mah Jongg cards do your Sleeves fit?

A: Our Small Sleeve fits the standard (small) NMJL card (4"x 5 1/8").
Our Large Sleeve fits the Large NMJL card as well as both the Large Siamese Mah Jongg® League card. (Just skim the bottom a little, per Gladys Grad and it fits perfectly.)
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! :)
