1. Pentel Energel needlepoints 0.5 (BLN75 or the BLN105); refills fit a Lamy Tipo. It's a great everyday pen.
2. Zebra Sarasa 0.5 - lots of variations of this pen with lots of pretty ink colors and cute body styles. I would use it more, if it were available in local shops. I don't order stationery.
I tried the often lauded Pilot G2, but wasn't a fan. It often would smear.
