Yup. They are awesome. Bought a bunch of them when I visited Japan. If you are buying from a store, do check out the nib size on the nib itself rather than the cap, as the caps are interchangeable and the body does not have nib size markings.

They are a pleasure to write with and if you write with the 01 nib size with the nib facing the opposite way than normal, you get an extra extra fine line (at the cost of huge friction) that leads to amazing fine drawings.
