Does the stationery in the prison have the name of the prison?

It won't show the name of the prison.

Generally, the prison logo will not be displayed on the envelopes sent by prisons, but it is not excluded that prisons collectively carry out activities related to letters and use special stationery and envelopes. In addition, there are envelope stamps or stamps, but the mobile phone stamps are stamped by the postal department that receives and sends letters, so it is impossible to see the prison mark.
