This listing is for .7mm HB lead mechanical pencil refills (12 leads). These pencil refills suit our Sierra pencils and our Slimline pencils.
Sometimes our website has difficulty calculating postage for pen refills. The postage should be $5 maximum to anywhere in Australia for up to 10 refills. If postage has been calculated incorrectly on purchasing we always refund the extra postage. Apologies.
