Cork Oak is an ink exclusive to the Kingdom Note store in Tokyo - a collaboration with Sailor. It's a complex brown with green and gold undertones. Slightly darker than in my photo.
Shipping I can include up to 6 different ink samples for the stated shipping fee. If you are ordering between 2 and 6, please select the 'shipping' for 1 of them and 'pickup' for the rest to avoid being charged multiple times for shipping.
NB: I only have limited supplies of each ink, and some are special editions/ store exclusives etc. that I can't easily get more of. I will do my best to remove listings as soon as any run out, but if I receive many orders in a short space of time this might not be possible. If you order something that has run out, I will contact you ASAP.
