I was grateful that I found honeybee stamps that actually sold this product with decent pricing. Brush EX's website is tricky to navigate due to foreign language.
Works great for Tombow Dual Brush Pen, Crayola Signature Brush Pen Set.
Does not work on:
-Tombow Fudenosuke Pens= really disappointed in that one.
-Kuretake Brush Pen
-Pilot Brush Pen
-Certain inks may discolor paper. I tested on HP Premium 32.
The concept or the purpose of this brush pen is smart- the execution stinks- pen leaks all over when shipping..AND when using- better off to buy refill and do yourself!
