Love the variety of sizes and colors---especially the saturated shades of blue!  It's perfect for adding a "pop" of color in our kitchen.  (I put the entire bag of blue ones in a large bowl on our breakfast bar).  I wish the approximate sizes of the individual balls had been listed in the description, but the largest balls are  2 3/4-in. in diameter and the smallest are about 1 3/4-in. in diameter.  The red collection will be perfect for the Christmas season!  Thanks Wayfair!
