Update: got it open!! Thank you all for your suggestions - I'll have a bunch of ideas if it happens again. This community is so awesome! (I put a picture with the ink swatch below in the comments)
Was very excited to swatch my new ink, but I cannot open it!! Used the jar opener portion of kitchen scissors, ran it under hot water - you can see some ink came out on that paper towel after that, but the lid is more stubborn than I am, and that's saying something. Any ideas, brilliant redditors?
