I picked this loofah online and find it quite comfortable to even use it as a back scratcher. I have had loofahs before which were hand held but this one with a handle makes life easy while having a bath.
When not in use in the bathroom I use it to scratch my back too. They are available in different colours Blue is my favourite colour. . One needs to wash them thoroughly after use and dried too. Else there is the possibility of bacteria setting in.
Soap applied on a loofah generates more lather and in a way soap lasts for a longer period.
