It is almost unbelievable how wasteful packaging waste orgy going on here: while one could insert 5 half Kuliminen readily in a small envelope and send, appears a package with 2-3Litern content, stuffed with so much paper that you have trouble packing the mines to find. This you have to imagine the size of a medium paperback, where then a note of 2x5cm (!!!!!!) inserted, which contains the 5 mines. I buy the mines now commercially and soon they (the Livescribe about 5-6mm shorter than standard short mines) up with a sharp penknife itself!
