Hot art tip for saving money:

You can refill your Micron (or similar) pens when they dry up. There are several YouTube videos, but basically pop the end off, shake out the sponge-tube, drip whatever ink you like into the sponge slowly until it's wet through, then re-assemble. Voila! Like new!

I think I originally discovered this through a post on Mastodon, but I’ve long since lost the original post, so if you’re out there, thanks OP!
