These are from three different manufacturers. I took photos of each manufacturer, so please take a look. Only the yellow ink from the second manufacturer is leaking, as shown in the third photo. All items are unused, but they have been stored at home for a long time. The expiration date is unknown. Since they are old, I don't know if they can be used, and there is a possibility that using them may affect your equipment, but I am very sorry, I cannot offer any warranty. Please use them at your own risk. Please consider this before purchasing.
