Zebra JF-0.5 Gel Ink Pen Refill, 0.5 mm, Black, 5 Refills per Pack (Japan Import) [Komainu-Dou Original Package] by Zebra

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
