This Wine Cup keeps drinks cold for 9 hours or hot for 3, and looks cool always. We personally prefer it for a nice glass of cab or chardonnay, but it really does work beautifully for beverages of every kind.
Dragonfly Tumbler works wonderfully for drinks of every type — from morning smoothies to water to 3pm coffee. Keeps stuff cold for 9 hours or hot for 3.
