Screw jar lid

cults3d

After the original lids have rusted to me I sat down and designed myself. These lids fit perfectly and close flush. The lids have a screw mechanism that does not jam but sits firmly. Lifting a full glass on the lid is possible without problems. The opening in the lid is adapted for standard glass / metal straws. These are so flush that they are freely movable but no insect fits between them. This protects the drinks in the summer from all unwanted with drinkers.
