uni whiteboard marker notification sensor medium square lead black Mitsubishi pencil 4902778761434 (10 sets)

It comes with a sensor that clearly tells you when it's used up, so you know when it's time to replace it.
Like the direct liquid type, it does not blur and allows you to write clearly and clearly to the end.
Stable erasability thanks to the development of a new ink (good even after drawing lines have passed).
Highly durable pen nib. Round core and square core can be used depending on the purpose.

With sensor informing the errand end definitely, I know exchange time.
I can take notes vividly well till the last without being able to graze it like a direct liquid type.
Removal characteristics stable by development of the new ink (I pass through a drawn line good after time).
A durable high pen core. I use a round wick and a corner core properly to a use and am possible.
