Luggage overweight is troublesome when we travel by plane. Here, we designed "suitcase+" a weighting handle. It measures the suitcase through a elastic PU spring. Colored number shows a weight in a small window. Therefore, you will know whether your suitcase is overweight. If it is too heavy, a built-in protector will take all the weight.
