Tear-jig is a kind of jigsaw puzzle that kids can take apart. Other puzzles only can be tiled for one time before throwing them away, which leads to a lot of waste. This specially-designed puzzle for little children has solved the waste problem perfectly. The more pieces the puzzle is separated out, the higher difficult level it reaches step by step. What’s more, saving more materials can bring children a sense of pleasure.
