I could definitely see it as something companies could use as giveaway promos at cons an shops and such. Like the way companies will give out pens and keychain fobs and suchlike with their name printed on them. For that market this could be good, though not so much KS material, as any company that's already having their name and logo put on pencils by any pencil or printing outfit can just have the dots added while they're at it with no need to buy from this outfit specifically. If the idea is a known old one like Cubs and Warlord say, it's probably not IP-able.
As a product sold to end users though... no.
