I always come back to buy this lead. It has a nice soft green tone and erases
easily (as long as you don't press too hard) and fades over time. So if you want
to use it for a rough sketch before inking, this should suffice. There are other
colors available if green isn't your preferred color to sketch with.
I teach Chemistry. These lead refills are really good quality. I have never
received one broken, and they only break on me when I have too much lead out
(3-4 clicks) and press too hard. The colors shown on the website are
surprisingly clear and accurate.
Green color is too light for my taste. Visibility on average book pages is not
vibrant like the purple, light blue, dark blue, and pink leads. Seems to
function well only on smooth white paper. Would not recommend the green or
orange colored eno lead colors. All of the other eno colors are fabulous!
