The Pineider Pen Filler is a travel size fountain pen ink tube that allows you to carry fountain pen ink on the go. Provides an easy way to refill your fountain pen and it’s portable. Maximum ink capacity is 10ml (.33 oz)
I have one of these for almost all of the inks in my small but growing collection. They make filling my pens much cleaner and they fit in my travel case whenever I go somewhere.
