I really think the V2 cartridges from Lucky Supply have improved. My only complaint with ALL cartridges, is that they tend to drip, and waste ink, and most do not hold much ink in the reservoir. The new V2 carts are definitely smoother, and I didn’t find a dud in the bunch. (I purchased several different groupings.) Thanks for making improvements to make our jobs easier. I have never seen Lucky sell anything bad, and will continue to go to them for most of my tattoo needs. Thank you.
