Designed for glass jar pickling and marination, this adjustable plastic press helps fully submerge vegetables in brine and promotes even contact. Key benefits - Flexible and deformable material that is easy to insert into glass jars. - Rotate to adjust height, fitting jars of different sizes and ensuring complete submersion of vegetables for thorough marination. - Smooth surface, durable and not prone to cracking, for safe handling and long use. - Vent or filter design enables air flow during marination, reducing air pockets. - Material: plastic. Usage scenarios - Use with standard mason jars to pickle vegetables such as cucumbers, carrots, or onions; insert, set the height, and press vegetables until fully submerged in brine. - Adapt to jars of varying heights; rotate to raise or lower the press so it works in short or tall jars and maintains consistent brine contact. - Ideal for home batch pickling or marinating, allowing quick setup and even distribution of flavor across multiple jars.
