X-Ray markers glow in the dark

X-Ray markers handmade lead letters set in resin.
I made these markers as a hobby for myself as I am a radiographer and I always lose my markers! Friends and colleagues have suggested I put them on here to sell so here they are! They're not perfect but I think that gives them a unique character.

Each set will be slightly different but I will do my best to make them look similar to the image here :)

Approx 1.5 x 2.5cm, if you would prefer a different size (see sizing chart) let me know on check out which one you would like.
