The economy cubes are 5-sided cubes made from 3/16" thick acrylic, with solvent welded glue joints for strength. They are great for those smaller display requirements where you need to place items on top. You can flip the cube over with the open side up to put items in them, like flowers and other center pieces for events, weddings, baby showers, and any formal gathering. SOLD AS A CASE OF 8 CUBES
