A bamboo sketch is a stylus by Wacom, and you can use it on a phone. I’ve never used it personally,
but that’s my recommendation. It’s around 65 bucks on amazon though, so my cheaper recommendation is this: 10 bucks for like 20 crappy pens xD they aren’t like electronic or anything, but they’re good for simple drawings.
Lol here’s the link for those:
