Syringe kit for pouring resin into tiny gap of mold
Great for refilling and measuring essential oil, inks, lubricants, sealants, glues, adhesives, solvents, light oil etc.
The plunger can pull right out of the back and the rubber seal can be taken off for cleaning as well.
They were perfect for what I needed.
Nothing out of the ordinary. Used to inject some resign on a fabricated airplane. Seemed to work fine
