The mini syringes are awesome! They are filled with a liquid that looks like real blood and are completely sealed. Everything has been annealed in my kiln for strength. While the syringe plugs may look delicate they are not, i wear mine to bed every night.
I can also put different liquids in them if you want, anything from different colors to stuff that glows in blacklight and stuff that glows in the dark.
The ones that have the glitter and beads in them can be customized too, just let me know what you would like me to put in there and ill let you know if i can.
