Silicone Straw Hole Grommets with Plugs for Mason Jar Lids 40 Pack

Perfect Fit: Designed to fit a 10mm (1cm) opening and reduce it to 8mm, these silicone grommets provide a secure fit for straw hole lids.

Wide Compatibility: Compatible with most of our painted metal and stainless steel straw hole lids.

Care Instructions: When used with tin-plated steel lids, remove the grommet before washing. This helps prevent water from becoming trapped beneath the grommet, which may lead to rust over time.
