Is it worth taking a decent quality scan of the decals as they're flat on the paper so that if in the future they can't be sourced from CK, repos could be made?
I did this for the last set of Bridgestone Decals I'd managed to get from Grand Bois in Japan at a similar cost
I need to check if they were unused but I think there were 3 full sets, so potentially 2 sets spare.
