Can I send a bottle to the prison?
You can't. According to the Prison Law of People's Republic of China (PRC), prisoners are not allowed to use ordinary gel pens, and the refills are sharp objects. Prisoners and their families are not allowed to take them to the prison for mailing, so it is not allowed to send refills to the prison. Prison refers to the place where convicted and undecided criminals are held, including not only prisons, but also detention centers and detention centers.
