Sweese 3401 Coaster Set for Drinks - 4 Pcs Bamboo Coasters with Porcelain Holder UNIQUE & ELEGANT COMBINATION - The combination of bamboo coasters with white porcelain holder looks super unique and aesthetic. They match well with any table theme, great for drinks at home or in bar, office, restaurant or parties. NON-SLIP BOTTOM DESIGN - Each coaster has a layered cork at the bottom to prevent the coaster from slide around. The bamboo surface isn't absorbent though, it won't stick to the bottom of cup like other coasters. DURABLE & PRACTICAL - Made from organically grown bamboo and hard-paste porcelain, mold-resistant, non-toxic and eco-friendly. They work well to protect your table from staining or spoiling the surface. EASY TO CLEAN - No stains are absorbed so they are easier to clean than other coasters. The holder is dishwasher safe and the coasters can be hand washed with soap and water, then wipe dry with a cloth.
