10ml TRUTH Glass Syringe Reusable with Metal Luer Lock, 1ml graduation (Case of 2)

Purchased specifically for mixing and refilling e-liquid.I was previously using plastic "single use" syringes, but they're a false economy for something I use every day.I'm no syringe expert, but these seem to be good quality; they certainly work well, and the  Blunt Ended 14 Gauge Stainless Steel Luer Lock Dispensing Needles  I bought to complement them, fit perfectly.The ground glass plunger part fits snugly and slides smoothly ( a very tiny bit of resistance ).The metal ( presumably Stainless Steel ) Luer Lock tip is solidly attached.Unlike the plastic syringes with rubber plungers, these have a very easy action, are a breeze to clean, and **have no parts to fail or wear out**(see update).Makes refilling my e-liquid atomiser tank much quicker, cleaner and a little more classy :-)UPDATE (6th May 2018): I used one of the syringes only until around January 2018, when it developed an air leak around the luer lock. I suppose the metal is bonded to the glass with some kind of "glue" which may have degraded through prolonged contact with strong nicotine juice. I don't know exactly, but the leak developed rather than being there all the time.I have since used the second syringe, keeping the leaking one in case I can fix it with some epoxy later. If the syringe I'm currently using also develops a leak, I will return with an update.I have removed one star because of this issue :(

Lovely quality- great delivery, unfortunately will not do what I had intended - but purely my fault/application's fault- NOT PRODUCT'SWill use them on another day hopefully.
