Optima offers coffee drinkers a new level of convenience not found in any other cup lid. What makes the Optima lid unique? To start, it provides users with a completely sealed beverage--no open drink hole means less chance of spilling or leaking. When ready to drink, just pull the tab open and lock it back out of the way. Most notable about Optima, however, is the ability to securely reclose the lid until ready to resume drinking. Not just once, but again and again. Give it a try and were certain you and your customers will quickly realize that no other lid provides the security, convenience, and quality of the innovative new Optima lid from Dart.
