Prepworks Prokeeper+ Bread Keeper

The container features a sliding, expandable design that allows you to adjust the length of the box to fit your specific loaf. By minimizing the amount of excess air inside the container, it creates a tighter seal around the bread, which helps maintain moisture and texture for longer periods.

Yes, the expandable design is specifically intended to accommodate various loaf shapes, including longer sourdough boules or standard sandwich loaves. You can slide the container to its maximum length to fit larger artisan breads comfortably.

Yes, the Prokeeper+ is top-rack dishwasher safe. However, for the best longevity of the clear plastic and the sliding mechanism, hand washing with warm, soapy water is recommended.

The container is designed to be relatively airtight to lock in freshness, but it does not feature adjustable vents. It relies on the snug, adjustable fit to control the internal environment rather than airflow.

While you can technically place it in the fridge, it is primarily designed for countertop storage. Storing bread in the refrigerator can actually accelerate staling due to starch retrogradation, so it is best kept at room temperature.
