These are English Measure, Metric will be available later. Plenty of these in stock and ready to ship. I also have some Titanium Keychain Pens made by one of my admins on my forum. These use a custom sized made by Fisher cartridge for this project. I have a couple of other titanium Items such as the titanium nanoStiker and a few titanium water bottles. I made a section on my store with just titanium items in it. http://www.jsburlysflashlights.com/...=184.108.40.206&act=&aff=&pg=cat&ref=titanium Here is something coming in February.
