CYMTOYPLAY Ice-ball-2in1-blue 2-in-1 Collapsible Silicone Ice Ball Mold 11oz 3.5x3.5x6.1in Blue accessory

Dual-function ice ball mold and cup

This blue silicone accessory creates a single large ice sphere and then converts into an 11oz collapsible drinking vessel. It is intended for anyone who wants slow-melting ice and a reusable cup in one compact item for home, gym or travel use. The food-grade material is BPA-free and dishwasher-safe for daily convenience.

Thermal performance and handling

The thick ice sphere melts slowly to keep beverages cold without rapid dilution. Silicone construction insulates the hand from extreme cold while the ice is inside. No power, noise or active cooling is involved; the product simply relies on freezer temperature and the sphere's low surface-area-to-volume ratio.

Build integration and portability

The mold collapses to 3.2 inches tall for storage in bags, car cup holders or gym lockers. A leakproof dome lid and reusable straw are included for spill-free sipping. It requires only a freezer compartment large enough for the 3.5 by 3.5 by 6.1 inch expanded form and a standard dishwasher rack for cleaning.
