These 1 oz clear tasting cups fit our 4 or 8 cup trays. These clear cups are also recyclable so they can be disposed of properly along with the matching trays. As with our trays, these cups help create a simple, easy tasting experience with your customers. If you are looking for a larger tasting cup, please take a look at our 2oz cups. Since our trays have the same multi-size cup holders, you can use either size cup in the trays. If you have any additional questions, please reach out to us at info@tastingtray.com
