Cute and elevated
Color: 10-Gold-100
These are really cute and really elevate our client experience at a minimal investment.
We offer a complimentary glass of champagne to our clients and we use these as an addition to serve juice, soda or water.
They are durable and pretty think, much better than using a thinner red solo cup and the gold addition the cups really makes them look expensive.

Great cups for any occassion!
Color: 9-Silver-200
These cups worked great for the rehearsal brunch and we were able to use the rest at one of the beverage stations at the reception. They were very good quality and the silver ring around the top added extra sparkle. Highly recommend!

Great Quality and Elegant Look!
Color: 9-Silver-100
I ordered these 9 oz silver-trimmed plastic cups for a dinner gathering , and they turned out perfect. The silver rim gives them an upscale, classy look great for parties or more formal events like weddings. They’re sturdy and don’t feel flimsy at all, even when filled with ice and drinks.
Guests complimented them several times, thinking they were real glass! Cleanup was easy since they’re disposable, but honestly, they’re durable enough to rinse and reuse if you want.
Highly recommend for anyone looking to elevate their party setup without spending a lot.

Good quality choice
Color: 9-Gold-200
Very good quality for a wedding. Used for wine with a larger size for beer. Great match and not flimsy or thin quality. Can be washed and used again as the gold band doesn't wash off easily and they still look new after one use, or toss.
