Well, this is new, but it's not good! The on-line store is having some problems with items that come in multiple scales. No matter which scale you choose, it adds the 10/12mm scale version to your shopping cart. I've put in a service request to the tech people, but this being Sunday (after a holiday, no less) it might take a while to get it fixed. Hopefully not too long! I don't think this will have an effect on any of the 6mm micro-scale products. Sorry for any inconvenience!
