What minimalist backpacks do you have?

TYP7: Bella, the main selling model at present (in fact, I don't see many people carrying this model at school), has many colors (but it is usually dark), and the difference from other models is that the bottom is yellow suede, and the zipper is yellow suede. The price of a treasure is 350~450MB. TYU7: solid color, suede at the bottom is the same as the bag surface, and the price of a treasure is more than 500 RMB. Tzr 6: 13 model, the color is bolder than TYP7, and the material feels different from TYP7. Prices range from 400 ~ 600 RMB to 600 RMB. T 19V: the latest model is similar in color to TYP7, and the bottom and zipper are made of black suede. The internal structure is optimized, and the price is more expensive than TYP7 100 RMB. TZ9A: It's cheaper, darker in color, and the bottom is non-suede, so the strength of the fabric is weakened, and the price is lower than TYP7. T50 1:: The cheapest one, because of its extremely rich colors (such as the starry sky with a high B grid), there are many people carrying it at school, mostly girls. ,

One-piece color design without suede. I like the texture of suede, but I am afraid that the yellow suede of TYP7 will get dirty easily, so I bought a navy T 19V, 460 RMB treasure. The space is large enough, the quality is great, the fabric is waterproof, and the internal design is reasonable, which is suitable for students' backs.
