Using your VitaJuwel Crystal Straw is easy. First, place the tourmaline quartz gemstone inside the borosilicate glass straw. Then, insert the straw into your drink and enjoy the natural energy the gemstone infuses. When you're done, use the plastic - free cleaning brush to clean the straw thoroughly. Make sure to dry it well before putting it back in the bamboo carry case. Remember, the size of the gemstones may vary, so handle them gently. Also, avoid dropping the glass straw as it can break. Keep your straw away from harsh chemicals to maintain its quality. By using this straw, you're not only enjoying a unique drink experience but also contributing to nature as a tree will be planted for every straw sold.
