I'm a very big fan of Lee Gear and own and use lots of it, but believe me you don't want to use the Lee lube because it's shit.
I use the Forsters case Lube http://www.midwayusa.com/product/300002 ... -oz-liquid
This will be available in NZ and you don't use much
My bottle is still half full after 5 years
Spread few drops over an unused Stamp Pad, roll the case over the pad take a cotton bud roll it over the ink pad then a couple of swipes inside the neck and jobs done.https://www.ordermax.co.nz/Office-Produ ... ed-2316900
