[Important Notes]
★ Due to manufacturing, there may be slight variations in size for each bag.

★ Some bags may have minor damages, creases, folds, unevenness, or dirt marks from the manufacturing process.

★ The material may have a slight odor upon arrival, especially when new.

★ As these items are imported from overseas and shipped rolled as shown in the product image, some bags may have noticeable wrinkles or folds depending on the production batch.

We inspect items based on whether we would use them ourselves. If minor wrinkles, dirt, or creases are a concern, please refrain from purchasing.

While these bags are slightly thinner than the heavy-duty types sold at home centers, they are recommended for those seeking cost-effective shipping mailer bags.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
