Product Care

To help maintain the beauty, performance, and longevity of your Sunday Mahjong™ pieces, we recommend the following care practices. With thoughtful handling and proper care, your collection is designed to remain elegant, functional, and enjoyable for years to come.

Apparel

Machine wash cold, inside-out, on a gentle cycle with mild detergent and similar colors.
Garment-dyed items should be washed separately until fully colorfast.
Use non-chlorine bleach only when necessary.
Avoid fabric softeners, which may compromise prints.
Hang dry whenever possible for best preservation, especially for embroidered items. Embroidered apparel should not be placed in the dryer.
Do not iron or dry clean.

Note: Care labels do not account for our specialized printing and embroidery processes. High heat may cause fading or cracking. We recommend washing new pieces separately for the first wash.

Hats

Spot clean with a damp cloth whenever possible.
If deeper cleaning is needed, hand wash gently in cold water. Avoid using brushes.

Drinkware

Ceramic mugs: Microwave and dishwasher safe, though hand washing will best preserve the finish. Handle with care to avoid scratches.
Glassware: Not microwave or dishwasher safe. Hand wash only.

Mahjong Tiles

Each set is crafted to be passed down, played with, and cherished. Treat your tiles with the same care you would give to any heirloom piece.

Please peel the plastic protector off by hand. Avoid knives or sharp tools, as they can scratch or nick the tiles.
Store tiles in their box or bag when not in use to keep them clean and protected.
Wash (mix) tiles by hand. Tile shufflers, while convenient, can be rough on the surface over time.
Clean gently with a soft, damp cloth. Avoid chemicals, abrasives, and dishwashers.
Do not submerge in liquid, as prolonged exposure may affect finishes or inlays.
Handle with care. Tiles are resilient, but drops and sharp impacts should be avoided.
Keep away from prolonged sunlight and extreme heat, including inside parked vehicles.

Subtle variations in color, finish, or patina are inherent to the artisan-crafted process — a mark of authenticity, not imperfection. Light surface marks that develop through regular shuffling and play are equally natural, and speak to a set well enjoyed.

Mahjong Mats

Roll mats for storage with the playing surface facing outward. Do not fold, as this may cause permanent creases.
For full cleaning, machine wash on gentle cycle in cold water with mild detergent; tumble dry low or air dry completely before rolling.
For quick touch-ups, spot clean with a mild soap solution and a soft cloth.
Allow to air dry completely before rolling for storage.
Keep mats away from extreme heat, prolonged moisture, and direct sunlight to maintain color and texture.
Do not leave mats in a hot vehicle, as extreme heat may cause damage.

Cards

Handle cards with clean, dry hands to maintain finish and color.
Store cards in a protective case or box when not in use.
Avoid bending, folding, or exposure to liquids.
Keep away from direct sunlight to preserve print quality.

Periodic Care & Inspection

Taking a few moments to care for your pieces regularly will help them stay pristine.

Gently wipe tiles and mats periodically to remove dust or light debris.
Inspect for signs of wear, such as loose stitching or minor marks, and address concerns early to prevent damage.

Storage & Handling

Store all products in a cool, dry environment away from extreme temperatures and direct sunlight.
Avoid stacking heavy objects on top of mats or tiles.
Use padded or protective cases when traveling with your collection.
Keep food and beverages away from your playing area to preserve the integrity of your pieces.
