Folding gift box Yupoo YSL messenger bag is very popular this year. The flip messenger bag is a self-recommended Yupoo YSLNiki new product. It is recommended by many bloggers. It retains Yupoo YSL's consistent rock and roll spirit and has an urban casual style. What is worth calling is that the material is made of imported tire cowhide fabric and is heavy-duty. Should the design be too cool or chic? The bag is not heavy. The capacity is large enough. The model is classic, high quality and durable. Size 23
