Using your VitaJuwel Crystal Straw is easy. Just put the orange calcite gemstone inside the glass straw and add it to your drink. The natural energy of the gemstone will infuse into your beverage. When it comes to cleaning, use the plastic - free cleaning brush that comes with the bamboo case. Gently scrub the inside of the straw to keep it clean. Make sure to rinse it thoroughly with water. As for storage, keep the straw in the bamboo case to protect it. Be careful not to drop the straw as the glass, though sturdy, can break if it hits a hard surface. Avoid using harsh chemicals to clean the straw as they may damage the gemstone or the glass.
