3 Oysters has a kit out with 10 bottles of ink that you can use to create your own ink! It's called "My Color" DIY Ink Kit, Four Seasons of Korea. 3 Oysters sent me this kit to do a review and I make a turquoise blue and a dark cherry red ink. 3 Oysters IG: 3oysters Sites I found that sell the kit: https://DeskBandit.com https://CityLuxe.sg https://vanness1938.com https://shigureinks.com If you know of other sites that sell this kit, please let me know and I'll post it here.
