Pls. Turn on the subtitle
I tested these erasers against the Stabilo Othello pencils which are considered darker than other brands, so the trace of graphite is expected. The reason is that I want to put them under challenge and the results can be more visible for filming purpose
One more thing, pls. Expect the shakiness of camera when I rub erasers hard on paper ... and sorry about my poor skill
Hope you enjoy it!
