Eco-friendly

水滴でコースターがふやけることもなく、軽い汚れは水でサッと洗い流せるので、半永久的に使うことができます。
繰り返し使うことでゴミの削減にもつながるので、環境にも非常に優しいコースターです。

The coasters will never grow with water drops, light dirt can be rinsed off with water, so it can be used semipermanently.
Since it also leads to reduction of garbage by repeated use, it is a coaster that is also very friendly to the environment.
