Sweet set of 3 small nesting boxes. 12cm cube (Monks Hill CR2)

This is a little set of cubic storage (or gift?) boxes in black and black and white. The largest one is about 12cm cubed and the other two fit inside. They each have a modernistic decorative feature, like a round “washer” on top. The big one is very slightly age-darkened inside but they look good and are strongly built, so quite substantial. I once used them for displays, but they have been stored for some time and I need to make space now. Please let me know when you could collect. (Not late evening or weekend, thanks.)
