As someone just learning to do brush lettering, I find myself purchasing just about all of the brush markers I see. I only just started so am very much still on the hunt for the marker I like best for it.
At this point, I have no complaints about these markers at all. They have a good sized barrel that fits nicely in my hand. It is also a good weight for me to constantly be moving my entire arm while using.
The actual brush tip also seems very durable. As someone new into brush lettering, I have ruined the tips on many of the other brush markers I have tried. So far, these have held up beautifully.
