Our original kawaii Happy Sun Bamboo Coasters are laser cut in 1/4" natural bamboo wood making them thick and dimensional. We spray a base sealer and semi-gloss clear top coat on each piece so they are resistant to moisture and very durable. Our exclusive coaster designs are beautiful in a living room and perfect for your coffee table, desk or office setting. They come as a set of 4 beautifully packaged in a clear gift box ready for gifting. Each one is approx. 4" x 4" and make a perfect handmade housewarming gift as well.
