Each glass can is made in our home studio. We use a high-quality heat transfer process that adheres specialty inks to each mug. This produces a permanent, long-lasting image that will not fade, peel or rub off, unlike vinyl or markers. DETAILS: ✿ 16oz glass can cup ✿ Natural bamboo lid ✿ Glass straw included ✿ Hand wash only ✿ Air dry ✿ Not microwave or dishwasher-safe ✿ Made in Flesherton, Ontario PLEASE NOTE: Each bamboo lid includes a semi-leakproof silicone seal, but the fit may vary slightly from cup to cup due to natural variations in both the bamboo and glass. Some lids may fit more snugly while others may feel looser - both are normal and not considered defects. These variations do not affect the functionality of the lid or cup. Thank you for understanding the unique, natural charm of these materials! Odours? ✿ Soak the top in vinegar or an eco-friendly alternative of your choice. Let air dry. ✿ You must properly clean and care for your bamboo lid to avoid
