How long does it keep food hot?

Vacuum insulation keeps meals hot or cold for hours, though exact times depend on preheating the jar and how full it is. Prefill with hot water for a few minutes before adding food to extend heat retention.

Is the spoon removable?

The stainless steel spoon folds into the lid and stays attached. It is meant for eating on the go and works best with soft or loose foods.

Is it dishwasher safe?

The description does not state dishwasher safety. Vacuum-insulated jars with powder-coated finishes are usually hand washed to protect the insulation and coating.

What is the air pressure release for?

It equalizes pressure so the lid opens more easily after hot or cold food has been sealed inside. This helps when temperature changes make the lid stick.

Can it be customized with a logo?

Yes. The smooth powder-coated body is designed for full-wrap decoration, and each item has a laser-printed QR code linking to the user manual. It is sold as a promotional product, often in bulk.

Is it good for soup and stew?

Yes, the vacuum insulation holds heat well for soups and stews. The 20 oz capacity suits a single serving, and the folding spoon handles thicker foods.
