PATENTED MAGNETIC DESIGN: Each straw cap has a clever magnet that lets them perch on top of your BrüMate Era and Resa lids when they are not in use, so you don't have to worry about losing them.
COMPATIBLE WITH ERA AND RESA: Our magnetic straw caps only work with our Era and Resa straw tumblers.
FOOD GRADE MATERIAL: Our straw caps are made a high quality, food-grade silicone.
