Glacier 4-Piece Ice Sphere Mold and Tumbler Set

Channel-Cut Crystal Tumblers Designed Around a 1.75" Ice Sphere — Slower Melt, Better Chill

Viski's Ice Sphere Mold and Crystal Tumbler Set is built around a single engineering idea: the tumbler and the ice are designed for each other. Each 9 oz lead-free crystal tumbler is sculpted with a circular channel at the base sized to the exact diameter of the 1.75" silicone ice sphere produced by the included molds. The sphere locks into the channel, maximizing surface contact between ice and glass, chilling your whiskey, bourbon, or spirit faster and keeping it cold longer than standard ice cubes — with far less dilution. Two tumblers and two silicone molds included; everything needed to build the complete slow-melt whiskey experience at home.

Why the Sphere-and-Channel Design Outperforms Standard Ice Cubes

• 1.75" silicone ice sphere molds (×2) — produce large spheres with less surface area than crushed or cubed ice; slow melt rate means less dilution in the glass
• Channel-cut crystal tumblers (×2, 9 oz) — circular base channel is precision-matched to the 1.75" sphere; sphere seats securely and maximizes glass-to-ice contact for faster, more consistent chilling
• Lead-free crystal — clear, brilliant glass with a premium hand feel; food-safe and spirit-appropriate
• Slower dilution — large sphere melts more slowly than cubed ice; preserves the flavor profile of whiskey, bourbon, aged rum, and other spirits served neat
• Complete gift-ready set — two tumblers and two molds; suited for whiskey enthusiasts, home bartenders, and as a premium gifting option
