These are tiered ice stands made out of a pale transparent yellow glass that has a touch of green in it as well. When I first saw these I actually thought they must be UV, since they have that color to them, but nope, no UV when I tested. They are solid and sturdy stands that work well with larger marbles, but would look all right with marbles in the 1.5" to 2" range also. 0 still available.
