*Please note: these rings are only compatible with the Big Mouth Bubbler® Plastic, they will not fit the Big Mouth Bubbler® EVO 2. They are also incompatible with the Big Mouth Bubbler® Universal Lid.
Best of all, cleaning is easier with a modular lid. The white disc is separate from the blue screw ring, so you can disassemble for a deeper clean. And the screw ring works seamlessly with both single- and dual-port lids.
Lid Plate Material: HDPE
