The puzzle is produced by GAN and is of very good quality. The Qiyi Snake has a mechanism that makes the pieces click into place so that it sticks to the shape you just created. The puzzle is durable and can handle being bent a bit. If you want to make it longer than 24 pieces, you can order more than one snake and connect them together.
MonsterGO Snake (24+ pieces)
MonsterGo Snake is a puzzle where the challenge is to assemble the straight “snake” into the shape of a ball. Using the 24 moving links in the chain, you can reshape the puzzle into thousands of different shapes and figures. The puzzle is a perfect pastime for both young and old! Something that distinguishes MonsterGO snake from other models is that the links can be both removed and added together with a simple push of a button. That means you can assemble an infinite number of MonsterGO snakes together or shorten it to fewer pieces if you wish.
