Our Stainless Steel Slide Under Drink Cup Holders are tapered to hold your drinks secure without spilling. These "Vegas Style" cup holders simply slide under a table's padded armrest. Additionally, these slide under cup holders will work standalone - even without tucking them under anything. Because this cup holder is constructed from stainless steel it retains its luster and is both durable and rustproof. Our standard size cup holder fits standard glass bottles and aluminum cans.
