They can be purchased from the store, except none have uncraftable text as far as I can tell. They also have some odd text string errors that seem to point to the description being bugged. Are the ones currently store purchased showing (not usable in crafting) when viewed through TF2? (ie. is it just an issue with third party viewers not being able to read the item info?) I don't know what you would craft them with or why, I just want to know because I collect things that have the text.
