That might be possible, yes. There are two options here.
The first would be extremely rudimentary equipment for a DIY "stick and poke" tattoo, which would involve a needle and pen ink. These tend to uncomfortable and prone to infection, but will cost significantly less.
The second would be much more refined equipment. A handheld tattoo machine, for example, would probably require two offerings - one for the machine and one to brand it with the sigil that would allow it to be powered and functional. Then there's a smattering of tubes, grips, needles, and ink, as well as the supplies necessary to sterilize the tattoo and equipment to prevent infection: cleaning soap, antiseptic, hospital scissors, tweezers, gloves, etc. This would obviously take a great deal more offerings. Of course, you could simply forgo the sterilization process entirely and chance magical healing instead.
