Household Washbasin, Thickened Plastic Washbasin, Laundry Basin, Large and Small Size, Student Dormitory Basin, Foot Wash Basin

It was a bit confusing because S, M, and L did not match the corresponding measurements. So I relied on the measurements, as these also corresponded with the increasing prices. However, I have now received the largest and smallest tanks, although I wanted the middle and smallest. What do I have to do to get the middle one delivered later? Otherwise, I really like the tanks!

A must have item in the kitchen!!!
