A big ass needle. Handy for measuring VG based nicotine.
Had absolutely no trouble sucking 8ml of VG based nicotine into the syringe to put into recently mixed liquid.

Top needle was part of a Marinade Injection kit that I found in my shed a few weeks ago.
It has a luer lock connection and is stainless steel. But the bottom is closed and it has 2 holes on the side so it can't drain a bottle.
Top, Marinade needle on 10ml syringe, it's about twice the diameter of a 16 gauge needle.
Middle, 16 Gauge needle
Bottom, 18 gauge needle on 3ml syringe.
