I had a Ohto Horizon pen that I lost a few years ago, I loved it. I tried to buy the same but it's not made anymore. Its successor, the Ohio GS01-S7, is pretty easy to find, it uses the same design and material (aluminium) as the Horizon, but doesn't have the side button to retract the tip. Anyway, the GS01 rattles so much while using it that it gets annoying. Why did you have to ruin it, Ohto?
