Re-Freez-R-Brix® Cold Bricks measure 7 x 5 x 1-1/2 inches and weigh 28 oz each, delivering extended cold retention engineered to maintain a uniform chilled temperature for over 12 days. Each brick contains a food-safe, non-toxic refrigerant material sealed inside a heavy-duty plastic pouch built to endure the physical demands of transit.

Their flat, brick-style profile stacks efficiently inside insulated shippers, maximizing thermal contact and minimizing void space — a practical advantage for pharmaceutical distributors, biotech labs, clinical specimen couriers, meal kit producers, and specialty food shippers managing temperature-sensitive outbound orders.

Sold in cases of 12, with each case weighing approximately 23.46 lbs. The consistent brick form factor simplifies placement planning when configuring insulated containers for varying shipment durations and carrier routes. Orders ship via parcel carrier.
