To ensure the longevity of our products, please follow these guidelines:

– Store Sleeves and Highlighters indoors at room temperature.

– Avoid exposing them to extreme temperatures or harsh chemicals.

MHH Sleeves

– Once adjusted to fit a specific Mah Jongg card size, the Sleeve can only be reused for that size card.

– Each Mah Jongg card should have its own Sleeve for optimal protection.

– To clean the Sleeve, use a baby wipe on both sides.

MHH Highlighters

– Use Highlighters only on our protective Sleeves to maintain their adhesive properties.

– To apply Highlighters, peel them from their backing and place them directly on the Sleeve.

– To move Highlighters, lift the colored corners.

– Store Highlighters flat on the Sleeve, away from creases, to prevent damage.

Care Instructions for MHH Highlighters

– To clean dusty or dirty Highlighters, use a drop of “Blue” high-quality degreasing dish soap.

– Create a lather on your finger and thumb, then rub it onto both sides of the Highlighter while rinsing under warm water.

– Gently pat dry with a microfiber towel or lint-free rag.
