These Amazon numbers are so great for birthdays! They are made out of cardboard (so some assembly is required) but come with a QR code that shows you how to put your exact number together. The lights come with as well (just need batteries) and you have affordable numbers! They are huge (4 ft tall to be exact). ⭐️👏🏻 LTKStyleTip LTKFindsUnder50 LTKParties
