The eraser itself works exceedingly well. Better then many I have tried in the "micro eraser" category. I love to draw with the finest diameter lead I can find (0.2-0.3mm). It is hard to find a good eraser to make corrections in the midst of fine
detail. Overall I am very pleased with my purchase. I will likely buy another one.
Please be sure you understand this is a VERY small eraser for detail work or
very small corrections.
Great pencil component. I think the 0.3mm Pencil works better (less lead breakage) in the thinner Sharbo
multi-pens (like LT3). I didn't like the 0.3mm in my CB8 as the lead seemed to break more often. The 0.5mm and 0.7mm work perfect in CB8.
I am practically obsessed with the Sharbo series multi-pens... I own 2 CB8, 3 LT3, 3 1970's original sharbo. They are just such an excellent product!
On a side note - 5mo or so daily use none of my pencil components have failed or
had any issues. Personally I prefer Pentel Ain Stein Leads.
