These 2 1/2" by 2 1/2" Luffa squares are really convenient and surprisingly durable! There are two sides to every flat cut Luffa. One side is very soft and is perfect for washing your face. The other side is not quite as soft and is awesome for kitchen and bathroom counters as well as general cleaning. We especially love this product because it's one of the purest forms of natural luffa sponge.
