Query: Very good quality product

This mug is very easy to hold while preparing the brush. Has a small depression in the bottom of the mug that holds the soap so you're not chasing the soap around bottom when lathering up the brush. Not usually wide awake in the morning, so having a rubber mug takes away the fear of having broken ceramic all over the tile floor or hard surface vanity top in case it's dropped.
