[Features]
This is a polyester insulation and sound-absorbing material with a relatively high density (30kg/m3). It offers excellent sound absorption and insulation properties and is made of a soft material. Its stable and solid construction allows it to be leaned against a wall (though it cannot stand on its own). Use it as an insulating material to help save electricity.

- Eco Mark certified material made from recycled plastic bottles, environmentally friendly.
- Contains no adhesives, thus preventing the emission of formaldehyde, a cause of sick house syndrome.
- No prickly sensation during handling, making it suitable for indoor use.
- The fibers effectively absorb sound energy, which is a form of air vibration.

[How to Use]
- Lean against a wall to reduce indoor reverberation from pianos, audio equipment, voices, etc., and to attenuate sound leakage to the outside.
- Place between noisy or vibrating appliances and the wall.
- Lean between a window and blinds to block external heat (for electricity saving measures).

[Notes on Cutting]
Please understand that White Q-on with a 50mm thickness is made of very strong fibers and has a high density, making it difficult to cut with a standard utility . Due to its strength, which is often used in professional soundproofing construction, we recommend using professional tools such as the following:
- Electric circular saw (with installed in reverse)
- Large tailor's shears
- A sharp replacement such as Olfa Special Black , used by folding about 8mm of the tip and always keeping it sharp.

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.
