Espresso Tokyo IceQuick Glass, a double-walled ice-proof glass with cooling gel, 300ml (gift box)

✅ [Let's start with the disadvantages of IceQuick Glass] IceQuick Glass is designed for cold or room temperature drinks, so it may not be able to cool hot coffee or other piping hot drinks properly. ✅ [Keeps drinks cold without ice!! Double-walled glass with cooling gel] No need to add ice, so your drink stays cold without getting diluted! ✅ [Ultra-special structure - Cooling gel inside the double-walled glass] IceQuick Glass, a glass that can be cooled, was created by injecting a special cooling gel into the inside of the double-walled glass. We went beyond conventional glass and thought long and hard about how to make deliciously cold drinks, resulting in an incredibly unique and unusual structure. ✅ [Keeps your iced coffee tasting exquisite] We developed IceQuick Glass to eliminate the common misconception that iced coffee and iced lattes taste bad because they're diluted by the ice. The frozen cooling gel thoroughly preserves the flavor. ✅ [Freeze in the refrigerator for about 4 hours to make it ice cold] Easy to use! Just place in the freezer for about 4 hours until it's frozen, then pour in your drink and enjoy.
