What do cba officials think of dribbling?
First, the appearance of 1. Leather: The leather color and feel of some fakes are very close to the real goods, but the thickness of the actual epidermis is less than half of that of the real goods, and the wear resistance is extremely poor, even it can be torn by hand. 2. Font: The characters around and at the bottom of the real ball valve are neat, clear, three-dimensional and concave-convex. The text of the fake ball is skewed and fuzzy, and there is no three-dimensional sense. The signature written by NBA President david stern on the real ball is clear and of moderate thickness, while the signature on the fake ball is either too thick or too thin, and the font is quite different from the real ball. (this needs to be compared with the real ball in the specialty store. ) 3. The bar code of the real ball is neat, straight and uneven. The bar code of the fake ball is untidy, twisted and flat. 4. Does the variety of basketball conform to Spalding's product catalogue? 5. Whether the price marked on the ball is too different from the company's regulations. 6. Check whether the bounce, perimeter and weight of the basketball are standard (the standard weight of the 7# ball is 600-650g/ ball), and whether the rotation center, ball opening technology and comprehensive feel are quite different from those of the same type of basketball bought before. 7. Plastic packaging: All products after 2007 have plastic packaging.
