They are 1.5". They are a bit dimensional but would go through the mail and would be fine inside a journal. They are pre-drilled at the top and can be assembled into a banner, put on a tree as an ornament or used on a package as a gift tag. I also sell 1" stars in the shop (see last picture for comparison). Please search "Rusty Little Stars" or simply "Rusty" to see more seasonal items you may be interested in. Please look at my other listings and if you would like multiple items, message me before purchasing. I consolidate shipping costs.
