Our drop-in cup holders are designed to fit into an opening specifically built into the outside of all sizes of our cooler line up.
The Oversized option fits most 30 Oz Tumblers (3" & 1/4" wide and 3" & 3/8" deep).
Our Standard size will fit most drinks (3" wide opening and 3" & 3/8" deep) but typically do not fit 30 Oz tumblers.
