Insulated food jar, 400-750ml. Verified for hot food, not cold.
Not yet stocked — supplier verification in progress.
A vacuum insulated food jar with a wide mouth, in the 400-750ml range. Independent testing found hot contents holding above the 140F/60C food-safe threshold for at least 6 hours — one protocol measured 193F to 144F over 6 hours, and the best-performing jars in a separate 12-hour test dropped only 46.3F over that period. We do not claim cold-food retention: every tested product in the sources found here failed to hold food below 40F. Wide-mouth lids are the reported failure point, so any batch needs a sample QC pass before listing. Landed cost is estimated at roughly £5-10 per unit pending a formal RFQ with suppliers; that number isn't confirmed yet.
