March Challenge - Acervuline

Day 16 of DDW's March daily challenge - Acervuline

I found this to be a tough one! I had plenty of big heaps that I could have photographed, but none that were in the least bit photogenic. In desparation it got down to these 2 Chinese balls, for exercising hand muscles, all nice shiny chrome, though not exactly smooth, 2 looking like a couple of mounds if not heaps.
