1.  Photos with the exception of photos with attached backing, framed photos that cannot be searched. 10 photos at a      time. It is recommended to write on the back of the photo your loved one's name and CDCR# 
2.  A calendar
3,  Blank greeting cards (no three dimensional cards allowed)
4.  Postage embossed envelopes, up to 40
5.  Blank envelopes (best not to send in more than 20 in one envelope)

12. No lamination.


In addition to letters sent through regular mail, inmates can also send boxes of personal items out to their families through R&R.  The cost to mail out items in this manner is the same as what the post office charges to mail packages.  See the USPS website for more information about the different mailing options and rates. 

Flat rate boxes are available in R&R for the inmate's use when mailing out packages.  This is a cost-effective and convenient way to mail numerous items, as the rate is the same no matter how much the box weighs.  When going to R&R to mail out these boxes, the inmate can either bring postage with him to cover the cost or it will be deducted from his trust account.
