Round Type 〈Size/Capacity/Material〉 φ105×H156mm / 450ml / Square Type 9.2 length x 6.2 width x 17.7 height Both are foam type. I was using them in the kitchen and bathroom. Since my child has grown up and wants to wash their hands by themselves, I'm selling these because I replaced them with different ones due to the possibility of them breaking. There is some slight wear and tear, but there are no malfunctions. They dispense the perfect amount of foam. I am not accepting price reductions, so I will not respond to such comments. Thank you for your understanding.
