Using the Metallic Tangle Jr. is super easy. Just hold it in your hand and start playing with it, bending and twisting the sections. You can also connect multiple Tangles Jr. with your friends to create longer chains. When not in use, you can coil it up and put it in your car, bag, or attach it to your backpack or key ring. Remember, when it's coiled, it's 1.5' x 2' x 1.5' in size, and it extends to 7' when you stretch it out. Each Tangle Jr. has eighteen 1' curved sections. If you order a pack of assorted colors, you'll get one of each color. If you order a box, you'll have a full case. To keep it in good condition, just keep it clean and avoid pulling it too hard to prevent any breakage.
