Operating Instructions
Airtight Seal and Closure
Each ProKeeper container features a secure clip-on closure and a silicone seal to maintain freshness. To close, align the lid and press down firmly until the clips engage. To open, unlatch the clips and lift the lid.
Filling Containers
The containers are designed to accommodate standard bag sizes of common baking ingredients. For example, the 4 Qt. Flour Keeper holds a 5 lb bag of flour, and the 2.5 Qt. Sugar Keeper holds a 4 lb bag of sugar.
Specialized Features
- Flour Keeper: The removable leveling bar inside the flour keeper allows for precise, level measurements directly from the container.
- Sugar Keeper: The flip-to-pour spout on the sugar keeper facilitates easy and controlled pouring of granulated sugar.
- Brown Sugar Keeper: To keep brown sugar soft and prevent hardening, soak the included terra cotta disk in water for 15-20 minutes, then pat dry and place it inside the lid of the brown sugar keeper. Re-soak as needed, typically every 6 months.
- Powdered Sugar Keeper: This container includes a leveling bar and a dusting tool for sifting powdered sugar directly onto baked goods.
- Mini Pro Keepers: These smaller containers come with dusting screens, useful for sprinkling spices or toppings.

Measurement Marks
Each container features clear measurement marks on the side, allowing you to easily monitor ingredient levels and anticipate when a refill is needed.

Maintenance
Maintaining your ProKeeper containers is simple to ensure their longevity and continued performance.
- Cleaning: All components of the ProKeeper set are dishwasher safe. For best results, place on the top rack. Hand washing with mild soap and water is also suitable.
- Drying: Ensure all parts are thoroughly dry before reassembly and storage to prevent moisture buildup.
- Terra Cotta Disk Care: For the brown sugar keeper, re-soak the terra cotta disk in water every 6 months or as needed to maintain its effectiveness.
Troubleshooting
If you experience difficulty opening a container, it may be due to the strong airtight seal creating a vacuum. Gently pry open one corner of the lid or release one clip at a time to equalize pressure. Ensure the silicone gasket is properly seated in the lid to maintain the seal.
