This product is made by high-temperature hot pressing of poplar wood and green tea. Compared to pine and cedar that release high concentrations of phenolic substance and formaldehyde, poplar wood is a highly harmless and environmentally friendly material. It possesses advantages such as moisture and odor absorption, being odorless, and easy cleaning. The tea polyphenols in green tea effectively control the growth of harmful bacterial while continuously emitting a refreshing tea fragrance. The combination os these two elements results in a dual effect, with a remarkable anti-odor effect!
