>>10896776>that tl;dr;Works fine for me, been using them for a couple of months, 20+ bottles in one location, zero smell (which is how you know it is not airtight), very easy to mix (flat bottom, can put a magnet inside).
The main advantage of the new HQParts bottle over their old bottle (or Dspiae or other random chinkshit) is the pouring opening. The threaded one gets gummed up eventually and cleaning it is a pain, the new one does not get gummed up at all even with the thickest primer.
