These Jumbo Ice Trays are exactly what I needed for cocktails and iced coffee. The six 1.5" cubes melt slowly, so drinks don't get watered down. The flavor-guard lids keep freezer odors out and prevent spills, which is a nice touch. The flexible silicone makes releasing the cubes easy once they're frozen. They stack neatly and save space in my freezer. Purple color is fun too. Only note: the cubes are large, so make sure your glass is wide enough.
