[split] Mechanical Pencils and High Quality Lead

[HPing]

My favourite eraser is the Pentel Ain Black. It is essentially dustless and does not seem to harden overtime (mine is 10 years old). It is not the absolute best at erasing but best overall IMHO.

The white plastic erasers might be slightly more effective but they produce more "dust". And start to harden after some time, losing effectiveness over a year or so. So buy smaller ones. I don't remember which was my favourite but I think it was the Pentel; the Tombow MONO and Staedtler are pretty good and easy to find.

The Japanese Yen has hit lows which drove the Plaza Accords of the 1980s. So Japanese stationery is excellent value IMHO.
