2. Look at the plastic packaging of all Spalding's genuine basketball. There will be an identity elevator indicating the material number of the ball and a small gray note that can be scraped off. A string of 16-digit authentication codes will appear after scraping. The 16 bit code of each ball is unique in the world and can be verified in Spalding official website.
3. After 2006, Spalding's main logo has completely cancelled Spalding's Chinese logo and used Spalding's English logo. Spalding's main logo adopts plastic relief shading, which means that Spalding's main logo shading should be made of plastic with regular small granular protrusions on it.
4. Look at Spalding again. Almost every ball will be printed with a bar code. The bar code of Spalding basketball is straight, and the thickness of a single bar code is even up and down, which looks slightly concave and convex when reflected. All Spalding new balls after 2007 will be printed next to the bar code. The unit price format of the ball is: unit price xxx yuan.
5. Continue to watch Spalding's genuine basketball. There will be four "Spalding" embossed glue lines at the intersection of the black gold grooves on both sides of the sphere (that is, the black stripes on the sphere). The four glue lines are arranged in a cross, with "S" on the left and "G" on the right. The whole sphere is a * * with eight Spalding knuckles on each side.
6. Let's look at the check valve. Because the production process is very elegant, Spalding's genuine basketball will never have a flat cut like leather cutting around the valve, but will be smoothly combined with the outer skin.
7. Spalding's genuine basketball production process is strict and complicated, and the center rate of each ball reaches 2 mm, so Spalding's genuine basketball is absolutely very round, which can be checked clearly with a turn of your finger.
