Do you think there is a market for people wanting a die on a keychain/keyring? I have made 3 in the past 5 minutes...took 2 attempts to get it right. I was thinking, I could buy the stuff required to make these at about 40p each, do you reckon I could sell them for £1.50 or so each, because all it is is a 12mm standard die (but in various styles and colours) on a small looped chain for your keys...
so whats his USP? I don't get why he would be worried about people copying something that he has copied.
