Gakken New Block Volume 500, a set of 489 pieces of 17 different types (11 pieces missing). It's at my parents' house, and I only played with it when I went back home, so it hasn't been used much. I've inspected each piece while wiping them down and removed any broken ones, but since there's a large quantity, I might have missed some cracks or dirt. Some of the pink pieces are faded. Please understand that these are used items. I will not sell individual pieces. They will be packed together in a plastic bag and shipped in a recycled cardboard box.
