Product function: No matter what, the store is bullying customers. The difference is more than 70 yuan. It is useless to contact anyone. There is no price guarantee within 15 days. I advise you to think twice. In short, I am very unhappy.

Product features: Moderate size, three-layer separation in the front and middle, smaller than the previous popular model, I still like the larger one. Appearance and material: OK, I prefer the previous classic popular model. Product quality: OK. You can’t see the size difference in the attached picture. In fact, the one I bought before is smaller.
