Weck Keep Fresh covers are BPA free and are suitable for storing opened jars of preserves in the fridge or when storing food in the freezer. As the lids expand slightly, there is a lower chance of glass breakage when food expands as it freezes.
The plastic covers also convert your jars into very handy storage containers. Use to store herbs and spices, reorganise your pantry or carry juice in one of the stylish juice bottles. The lids are made of flexible BPA free plastic and snap onto the jar. They are airtight but do not have any sort of seal with them.
Note that the product may differ slightly from the photo and may be branded either Weck or Rex.
Lids come in 5 sizes: extra small 40, small 60, medium 80, large 100 and extra large 120. The number on the glass lid denotes the size lid your jar takes. Extra Small = 40mm, Small = 60mm/ 2 3/8", Medium = 80mm / 3 1/8", Large = 100mm / 3 7/8 ", Extra Large =120mm. Check your jar to see which size yours is.
Medium suits the following models: 976, 900, 901 and 908
