【Energetic Color Combination】Inspired by the culture of ink wash painting, it has a simple design and a luxurious appearance. The coasters feature a wonderful ink wash painting pattern, colored in white, blue, green, yellow, and red. 【Excellent Absorbency】Made of natural diatomaceous earth, it has strong absorbency. Compared to silicone coasters and ceramic coasters, it has superior absorbency. You will no longer have to worry about water stains from drinks. You can enjoy water, tea, and coffee even more. 【High-Quality Materials】Diatomaceous earth makes up over 70% of the material. The back is made of non-slip EVA material, which prevents scratches and damage to the tabletop. The coasters will not stain tables or fine furniture, and they won't stick to the cups! The non-slip material increases friction, making them less likely to slip and allowing them to adhere firmly to the table. 【Novel Decoration】Comes with a stylish box. The coasters are 3 inches in diameter and are suitable as decorations for kitchens, living rooms, bedrooms, and offices. Also, it's a great gift for friends, highly recommended. Tips: 1. Due to the diatomaceous earth material, the product is hard and fragile, so please handle it with care. 2. Be careful when using, as severe colored water stains, coffee, milk tea, and colored juices may cause staining. 3. If the absorbency decreases, wash it with room temperature water and then dry it in a cool, shaded place, avoiding direct sunlight, otherwise, it may cause warping and cracking. 4. Do not wash with hard cleaning supplies such as metal scrubbers, to avoid scratches. The box will be shipped folded.
