1.    Handle With Love — Avoid Dropping 
Just like a baby, your flask doesn’t like falls. Dropping it can cause dents, misalignment, or even damage its insulation. Carry it with care, always!
2.    No Sharp Objects, Please 
Avoid using metal utensils or hard scrubbing tools on or inside your flask. They can scratch the surface or interior, compromising both its appearance and performance.
3.    Dress It Up with Protection 
Outfits for your flask? Yes! Use a protective pouch or silicone bottom cover to guard against scratches and impact — it’s cute and practical.
4.    Limit Contact with Oils 
Frequent contact with hand creams, body oils, or greasy hands may cause surface discoloration or stains over time. Keep your flask’s finish fresh by handling it with clean, dry hands.
5.    Use Mild Detergent to Clean 
Be gentle when washing — opt for a mild dishwashing liquid and soft sponge. Harsh chemicals and strong detergents may affect the coating or insulation performance.
