Like this little pen. Filled it with OTR 970 hard to buff ink. Nib doesn't stay super juicy, find myself pumping it a lot but still a great pick up. The refilling issue aint all that big of a deal just get some pliers and lay down some paper to catch any residual ink you're about to spill pulling it apart. Id rather have a tight seal than a leaky one anyways.
This could be a perfect little marker body. Size is amazing. Flow is great with Magic White. The nib itself is something to be upgraded. Broke down a little too easy. But you can cut more replacements if you're creative enough.
Best marker body of all time. If you're leaking or streaking. You're not using it right. I'm going to cut mine down an inch or two to make it shorter. Magic mixed with Molotow is a tough combo. Needs back pressure. Loosen back cap for more flow.
