The improved companion cube design. This one uses smaller rings, but there are more of them, so it is slightly easier to work out a heart shape on the sides.
I made this one for myself, and a blue one for  Phosphorous_Tick

Improved cubes are $28+s&h each or $50+s&h for a set.

**shipping and handling is roughly $10-$15 throughout Canada and the states, and includes insurance and tracking. A more accurate s&h quote can be given upon request.
