Running out of ink in your favorite multi-pen?

These 68mm D1 style metal refills from CaoDuRen are just the ticket.

They're a standard size that fits a ton of pen brands, like Zebra and Platinum, and many other multi-pens that take the D1 refill.
Just a heads up: these are 68mm long, so make sure that's the size your pen takes before ordering.

They're brand new, metal construction, and ready to write.
