These centerpieces are about 5" tall & are single-sided. They measure 12" tall after they are adhered to the dowels. Please leave a note at checkout with the number you would like to have. I have other sunshine themed items in my shop, including cupcake toppers & banners. The centerpieces will be shipped in a box, using USPS First Class mail. If you would like to upgrade to Priority Mail 2-3 day, you can purchase an upgrade at checkout. Thanks! Sunshine Birthday Centerpieces
