Can inmates receive letters written in pencil

Yes, in most cases he should be able to receive it.

Letters written in pencil and drawings done in crayon are usually allowed, especially when they come from children. Facilities generally allow:

• Handwritten letters (pen or pencil)
• Simple drawings or artwork
• Personal messages from family

At a place like Luna County Detention Center, the mailroom will still:

• Open and inspect the letter
• Check for anything that violates policy

As long as the letter does not include anything prohibited, it should go through without a problem.

A couple of tips to be safe:

• Do not include stickers, glitter, or anything glued on
• Keep it to paper only
• Make sure his full name and inmate ID are on the envelope

Bottom line
A child’s letter and drawing like that is exactly the kind of mail facilities expect and allow. He should receive it just fine.
