Yes to both. InmateAid's magazine store carries a wide selection of titles across many categories, and Inked is available in the art section. You can order it directly through InmateAid at inmateaid.com/shop/magazines, and it will be shipped to your inmate at their facility.
Magazine subscriptions are one of the most practical gifts you can send to someone doing time. Reading material breaks up the monotony and gives an inmate something to look forward to each month. Inked, in particular, tends to circulate through a housing unit long after it arrives, so it goes further than most.
Keep in mind that some facilities have restrictions on certain magazine content, so it is worth confirming with the specific institution that Inked is on their approved publications list before ordering. Most art and tattoo publications clear standard facility review without issue, but a quick call to the mailroom never hurts.
