Iwata Main Lever (TAKUMI) I6124

I have all of the Kustom Series brushes, I always wanted to try the square trigger, but all the Kustom brushes use the same style trigger as the HP-CS (with the plunger pressed into the trigger). I was nervous to see if these would work in my Kustom HP-CH & Kustom Micron (note that’s Kustom with an “K”. It’s not a standard Custom Micron, they have been discontinued for a while now, unfortunately) and they work fantastic! I find them to be far more comfortable for me. I’m going to order one for my Kustom CS as well and may try the Blair spring in my K-CM for as much control as I can muster!

Bought this to replace the round trigger on my Revolution CR but the improvement is not as dramatic as the I5454 on my other airbrush because the air valve spring of my CR is lighter so the original round trigger didn't feel heavy to begin with. Still, this square trigger provides better grip and finer control. However, I just like the I5454 a little better because it has a slightly bigger surface.
And to anyone looking for a lighter needle spring, the spring in Zebra SARASA gel pen is the perfect fit with the right amount of strength. I am sure there are other affordable alternatives but this is what I discovered by chance.

Works perfectly and the delivery was fast.

I was just going to replace the air valve /guide on my HP-CS and saw that the Eclipse Takumi trigger was an optional fit so decided to try it out. I prefer it a lot more than I thought I would -feels overall more stable. It’s not perfect on this brush though - seems like it’d be more comfortable with the trigger resting behind the first joint of my index finger, but with the cup mounted so close there isn’t room to position that way. Still, feels better than the stock CS trigger. Worth it for sure.

I love my Iwata Eclipse HP-CS, but the Main Lever can be uncomfortable with long use, this simple change corrects that problem.
