Pilot Iroshizuku inks usually come in a 50ml bottle, or in this 3x15ml pack.
The previous time I looked at them they came in these pre-defined sets of three and none of the sets appealed to me so I never got them. But I while back I noticed that Tudos let me pick what ever combinations I wanted, so I ordered a pack.
I like the bottles themselves. They are not as nice as the 50ml one, but better than most. They are made out of glass so no worry of them flipping over if you leave a pen in it.
The price is more or less the same as a 50ml bottles, so the price per ml isn’t that far off from getting the large bottle. And this is a great option if you care more about having more different inks than getting the most ink for your money. And if you like me have a limited amount of space for ink or don’t like to have a lot of inks laying around the 15ml is a lot more manageable than a 50ml.
What I really disliked however was that I came in one of those horrible gift boxes I hate, that only service one purpose and that is to fill up my garbage bin.
