Best Toy - Stacking/ Nesting Cups

I wanted to get some stacking / nesting cups for Erbie and tried Hamleys to no avail, but then joy of joys was given some, so I can't tell you who made these but they are just one of the best toys for Erbie at the moment. They provide hours of entertainment, he has recently started putting them back inside one another. If you build a tower, it's fun to knock down or we are almost getting him to balance the last one on the top. They are good for learning to count, dexterity, colour matching, they roll, they can dissappear and reappear from inside each other, endless possibilities from such a simple concept, we likey and highly reccommend.
