Ghislaine Adjustable Straw Cover

This innovative design addresses the common issue of fixed-size silicone sleeves not fitting all straws. With so many brands and sizes of straws available, it can be challenging to find a cover that fits perfectly. This adjustable cap is designed to accommodate straws with a diameter between 6-10mm, ensuring a snug fit for a wide range of brands and sizes. Before purchasing, please verify that your straw falls within this size range.
