So impressed by these! I have mostly just used the 1003RL from my sample pack so far and one or two of the others but they had such good ink flow while still being so tight. I didn't realise how much I enjoyed the grip on them either till I went back to my old carts. Converted.
I LOVE Metal Fingers, all needle groupings I have ever used from this supplier have just been amazing. I use them for Fine stipple shading/Dotwork/Mag Shading/Blackwork.
