MUJI Reusable 3 Layer Mask is made of 100% cotton and comes in a pack of 2. Antibacterial and treated with deodorant, these masks have excellent breathability and water absorbency. With nose wire inserted, the mask is large enough to cover the face firmly without creating a gap. Each mask can be washed and reused up to approximately 30 times. Suitable for daily use and not as a substitute for medical, surgical or respiratory mask. Available in limited quantities at selected stores (RM38.90). Care Instructions: 1. Prepare a tub of warm water of about 40℃ and add neutral detergent. 2. Soak the mask for 10 minutes. 3. Rinse the mask gently without rubbing. 4. Discard the tub of warm water and fill with tap water to rinse away the detergent on the mask. 5. Drain excess water once washing is done and use a clean towel to pat dry. 6. Reshape and let dry in a shaded and well-ventilated place. The mask may shrink when washed, but it does not affect the quality. Recommended to wash it once a day or when it gets dirty.
