Dry the dog well, but unfortunately this moldy towel when not in use

Bought two of these have Easidri towels, and at first I was really excited by the drying effect. The Easidri towel fits comfortably in your hand, and takes a lot of water from the dog. Have always treated according to instructions in the towel, and wet back done in the can.
Now after 3 months did not use, I wanted to use the towels again. But unfortunately both were good moldy, and the can was down moldy.
The stench no longer goes away despite vinegar.
I think with such a high-priced product may not be.

PS: It takes time to write reviews on Amazon. It would be nice if I get some feedback. Many Thanks!
