Yupoo Yupoo COACH Boston bag is classic and never goes out of style. The Yupoo Yupoo COACH classic presbyopic series looks good no matter what color it is paired with. The Boston bag is a bag commonly used by students at Boston University in the United States. Personally, I think it is a pillow bag with a pillow shape that can be worn by passersby to look like a star. The visual sense is super versatile, but it does not hinder its classic spread and never goes out of style. The biggest advantage is that the leather is very enlarged and is not easily deformed by heavy objects, giving it a very solid feeling. It can also bring out a capable impression, whether it is formal or formal. The suit or fresh dress is very suitable for the color range. It is probably the most popular one. The size is about 1218cm.
