Care Instructions

🫧

Washing Machine wash cold, gentle cycle. Turn inside out to protect the knit design. Use mild detergent — no bleach or fabric softener.

💨

Drying Air dry flat or hang to dry. Avoid tumble drying — heat can shrink the knit and fade colors. Do not wring or twist.

📦

Storage Store folded loosely or slipped onto the bottle. Avoid cramming — knit memory holds best when uncompressed. Keep away from direct sunlight.

✨

Longevity Tips Remove the cover before putting your tumbler through a dishwasher. Spot-clean small stains with a damp cloth for everyday maintenance.
