When you work at a school, Sharpies and dry erase markers are a hot commodity. At the beginning of the school year, they're everywhere. But by the last few days of school, they've all either been taken or mostly dried out.

I've always dreamed of refillable markers that work like a soda filling station at a fast food restaurant. You just hold the marker up to the spigot for a few seconds and fresh, bright ink somehow fills it.

Knockoff Sharpies are the worst...an insult to paper! Good luck finding some real ones soon!
