Silicone Straw Hole Grommets for Mason Jar Lids 5 Pack
These grommets fit in a 10mm (1cm) hole and reduce it to 8mm. They will fit most of our painted metal or stainless steel straw hole lids. Our solid colored lids and daisy lids have smaller holes so they will not fit those.
We don’t recommend grommets for an 8mm or larger straw (like our Safer Rounded End straws). The straw will push the grommet against the sharp metal and cut through it.
