Using your VitaJuwel Crystal Straw is easy. First, take the straw out of the bamboo case. You can then place it in your drink, and the sodalite gemstone will start infusing the drink with its natural energies. When you're done, use the plastic - free cleaning brush to clean the inside of the straw. Make sure to rinse it thoroughly with water. As for maintenance, store the straw in the bamboo case when not in use to protect it. Avoid dropping the straw as the glass is sturdy but can break if it hits a hard surface. Also, don't use any harsh chemicals to clean the straw, as this could damage the gemstone or the glass.
