Isn’t that cute? Mama piggie feeding 3 little piglets. Wait, what? This is USB Hub and 3 USB TF Card Readers? This deal keeps getting better and better! There is even more than just pigs – you can choose from: PigChum, CatChum, or DogChum. They are extremely cute and also very practical; the beauty of the Animal Hubs is that they allow the customer to not only choose the size of the memory in the product, but it also allows them to use their existing Micro SD cards.
