I think it looks like a fake, it doesn't have 'Tamagotchi' or 'Tamagotchi Connection' written on the top of it, and the it looks very plain, most tamas had backgrounds (apart from black V1 and some others)
But it doesn't matter if its a fake or its real, its still a Tamagotchi! sort of
Hope i helped locky458! and have a super tama-talking day!!!
