Plain, regular greeting cards. While this may seem boring, even a plain, regular greeting card is much appreciated by the inmate.
If any greeting cards are deemed by the prison mail staff to be inappropriate, the cards will not be delivered to the inmate and may be disposed of. Check with your inmate's institution to get a clear understanding of any restrictions, including size and quantity.
Greeting cards can be purchased at the store and mailed by you, or greeting cards can be purchased online, personalized, and sent directly to the inmate. There are many online greeting card websites. You want to make sure you are purchasing a regular greeting card, not an e-greeting card (digital).
