Good choices
Heavy-duty insulated coolers, expanded polystyrene (foam) shippers inside a cardboard outer box, and purpose-built dry ice storage chests.
Avoid
Glass jars, sealed plastic tubs, screw-top bottles, or any container that locks airtight.
Can dry ice damage a cooler?
Extreme cold can make some plastics brittle. Many cooler makers publish whether their product is dry-ice compatible — check before use and add a layer of cardboard between ice and liner if unsure.
Dry ice releases carbon dioxide gas and requires proper ventilation. Handle only with insulated gloves, and never seal it in an airtight container.
