Hi. I have a dragonhawk rotary pen and the Poseidon cartridges fit. Yes, I believe it will fit any rotary pen.

So do I get 10 of each ?

5rl 7rl 9rl 5rs 7rs 9rs 15m1 21m1 15cm 21cm 10 kind sizes. And 5pcs/each.Total 50pcs. RS is 0.35mm. Others are 0.30mm.

So is it 10pc or 50pc? Top description said 50pc but bottom description said 10pc.

I got 50 needles but make sure you click the correct one cause i think they do have some 20 to a box
