If the glue is broken, dip it in the basketball repair shop, or get some 502 yourself, but be careful, just paint the edge, or get some protection outside and then paint it. Just don't touch outside. However, please note that the glued basketball is very uncomfortable due to the change of balance and feel, and it is very easy to open the glue again at the glued place.
In addition, the most important thing is, if you are a football fan, please treat your basketball well. It will be your best friend. You can throw it when you are angry, you can fight when you are happy, and it can always accompany you. However, the biggest enemies of basketball are water, oil, heating, ass and your big feet.
Water will lead to leather aging, and the adhesive itself will undergo oxidation reaction. Just like basketball, the leather surface will also age. Oil can dissolve some glue for sticking basketball, which is easy to open, and it will also react chemically with leather surface to make it aging. Heating, I don't know if you are from the northeast, if so, then remember that basketball can't be baked under heating, it will bulge and deform. Ass will lose the prototype of your good basketball sitting posture, which will lead to a decline in balance. People will call it a ladle. Kicking is countless times more harmful than ass, and I have even seen a big bag bulging with one foot.
Please take care of your basketball. Is your good friend.
