These "Vegas Style" Plastic Slide Under Drink Holders with Cutouts simply slide under a table's padded armrest. The lip at the bottom of each cup holder allows them to slide under the rail of a table for a secure place to rest your drink. With cutouts on the sides these holders will accommodate almost any type of cup or mug and their smoke color is sure to compliment your decor. Additionally, these slide under cup holders will work standalone - even without tucking them under anything. Our standard size cup holder fits standard glass bottles and aluminum cans. The inside diameter measures 2.75 inches by 2.75 inches deep.
