- What you get: 2-pack ice block molds for ice baths, total capacity 6 lb. - Superior design: Large silicone molds made from high-quality silicone for durability and long life. Moderate softness with thick walls helps prevent collapse when filled, and the four-corner reinforced frame keeps ice blocks square and makes release easier. - Excellent replacement for ice packs: Giant ice cubes melt slowly, taking 7–9 hours to fully melt at about 71.6°F (22°C). They maximize cooling duration and are ideal for extending cold exposure in an ice bath or cold plunge. - Ready for cold baths anytime: Create large ice blocks at home to avoid supermarket ice. Freeze in advance, then use after exercising or when you want to relieve muscle soreness and uplift mood. - Easy to use and release: Fill with water, freeze for 12 hours to produce 6 lb of ice. To release, open the four sides of the ice box and remove the ice cubes. For easier demolding, wait about 30 seconds after removing from the freezer. After use, dishwasher safe for cleaning.
