It's the right size and it prevents my bars from scraping the solid soap-bar-holders. However, the wood turns black because of moisture and I'm not sure what to do because the bag is precisely designed to wick moisture. Regardless, I like it because it wicks moisture effectively and I think it could be drying my bars faster than the solid soap-bar-holders.
Since the fabric is sort of rough, it's not uncommon for the soap and conditioner to slowly build up in the fabric. However, much like a cast iron pan, once the fabric is sufficiently saturated with shampoo or conditioner, everything flows well.
