I bought this one on Amazon https://www.amazon.com/dp/B07X1R442K?ref_=cm_sw_r_apan_dp_QWQ6WXPG69X82JH1R0C6

Get a scale that goes down to 0.001g and you should be good. That will cover your for the very small 10mg, but also still be good for larger doses, as well.

This one is a reasonable price and fits the bill. I haven't used this particular one, but it seems to have decent reviews, as much as you can trust Amazon reviews lol

Edit: it sucks

I use this one, I like that it goes to 0.001g so I can get really specific with my dose
