Some of the toys I'm nostalgic about are kind of environmental plastic disasters. I loved these "push pens"
But there's no way to refill them. You just have a lot of plastic bits when the lead runs out...
I wonder if that could be redesigned...
The idea of having a bunch of ready sharp points of lead is nice.
@futurebird Can't seem to get to your server atm to read the other posts, but I guess I have to ask the question others are probably already asking: why not just a mechanical pencil with fine lead? Some can get pretty fine and I'd argue sharper than those points are for the finest ones.
0.5 is a pretty ideal size for a fine tipped mechanical pencil that can be used for just about anything.
I remember the pencils in the image. Been a long time. I didn't really like them that much personally. Once I went mechanical I never looked back.
