Washing too hard. The nba75th anniversary jersey is the NBA75th anniversary Lakers fan version jersey, including James No. 6 and Davis No. 3. There is a diamond-cut NBA logo on the back, which shines three-dimensionally. When the jersey is sold online, there are precautions for washing. Since the diamonds on the back are relatively fragile, machine washing cannot be used when cleaning, and only warm water can be used. Wash gently. Washing too hard will cause the diamond logo to peel off. Once the paint peels off, it is irreversible.
