Review on 🥤 Tervis 1338135 Sayings Insulated Turquoise: Keep Your Beverage Hot or Cold in Style by Marvin Short

Used to prepare iced coffee drinks or Crystal Light drinks mixed with water and seems to keep ice liquid well chilled. The lid has a sliding opening and the mug can be used with or without a straw. Although the lid snaps on tightly, it's not tight enough to prevent the drink from spilling when I try to mix the contents by shaking the mug. When the sliding lid is pressed firmly, it works better but still drips out of the hole.
