Jumbo Stacks are great for PE teachers who want to add something new to their sport stacking program. They are a perfect way to turn up the fun and add more movement simultaneously. Floor relay games for kids and doubles stacking are a whole new challenge with these large scale cups. Three different color sets of 12 Jumbo cups are included so the whole class can participate at once. Each Jumbo Cup is 27cm high x 23cm diameter.
