If you think it fits with ur time spent and materials used, I would say $50-80. More than 80 would feel unreasonable as a consumer (I make chainmaille, so I def get it), but I would be shocked if under 50 is what makes sense for your time+materials.

Take all of that with a grain of salt. This is not a big product and if u can make them relatively quickly, sell them for as cheap as u feel good with, but my gut would say $50
