"Outside of my art-life, I sell car parts. I find it easy to refer to items with numbers when writing out my records than to type out the whole title. If I need a reminder as to which is which, I have a list for that. I'm also interested in knowing when I've turned my inventory, and numbers are the easiest way for me to see when that happens, but I would NEVER put inventory numbers in descriptions or titles on my Etsy shop. Everyone has their own style!"^^<http://www.w3.org/2001/XMLSchema#string>
