Installation Method: This is a water-application type that can be easily attached by spraying water on the window glass with a spray bottle. Features: High transparency means the room won't get dark, and it offers moderate privacy and condensation control.

- Color: Clear
- Use: Insulation material for window glass

Purchased for ¥1400 per roll.
With the hot weather approaching, why not enhance your air conditioning efficiency?

I purchased this with the intention of using it, but I haven't used it, so I'm selling it.

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.
