Using your VitaJuwel Crystal Straw is easy. Just put it in your drink, and let the natural energy of the carnelian gemstone infuse your beverage. Make sure the straw is fully submerged for best results. When it comes to cleaning, use the plastic - free brush that comes with the set. Gently scrub the inside and outside of the straw to keep it clean. Avoid using harsh chemicals as they might damage the glass or the gemstone. Store your straw in the bamboo case when not in use. This will protect it from getting damaged and keep it clean. With proper care, your VitaJuwel Crystal Straw will last you a long time and keep adding a touch of natural energy to your drinks.
