I bought it but never used it. I left it outside, so the color has faded from sun exposure, but there is no damage. A carefully crafted product using 100% domestic ingredients. It can be used to create layouts for moss balls, shelters, and terrariums. This convenient modeling material can be shaped as desired and allows for plant cultivation! Enhanced with zeolite! Significantly improves fertilizer absorption and prevents root rot. Please refrain from purchasing if you are concerned.
