Excellent fun for developing cooperative play. Great for muscle development. Stimulate the imagination for creative playtime. Use alone or connect to other Pacific Play Tents. A total see through design for great fun. Kids love to wiggle and squiggle through these "mesh" tunnels. Allows the younger children the ability to see everything, but still provides hours of fun. The sturdy spring steel construction and fine mesh see through design will provide enjoyment for kids from 3 and up. Older kids use these as "dancing tunnels". The tunnel collapses down for easy storage and carrying. Wipes clean with a damp cloth.
