This is a supe useful ink vial holder I designed to take my ink along when I travel so my fountain pens can keep writing! It stores 3 x 5ml ink vials. The vials are from Amazon and measure 48.3mm with the cap on and 16mm diameter. The come with a pipet, so I shortened the pipet and designed a lid that can house it, as shown in the pictures. The pipet fits in nice and snug, but blowing into the hole on the other side releases it. I also added an ink well into the design, so you can transfer the ink from the vial, get it into the pen and then pour out the remaining in back into the vial. The pipet is used to transfer the ink from the vial and visa versa if you do not want to pour it back.

Enjoy! Has improved my travel experience!
