These black syringes and caps are for UV resin. You can now mix up your colors of resin and store them in these black syringes and not worry about it hardening in the sunlight while you use them. Super easy to reuse too, just mark the color you used in them with a label and refill when needed! 

These syringe holders help to fill your syringes and not make a huge mess!
