Moldy bristles in less than two weeks.
Mold. Less than two weeks of use and mold. Ew. The wood does not seem like it's properly sealed for a product that is expected to be used with water. I threw them away. Not even worth trying to return as it didn't feel hygienic.

Looks nice
Color: Silver
It looks very nice. It has a streamlined design, not big and bulky. Quality is ok. I really like the look of it.
