Blue Cobalt Bottles These Cobalt bottles are beautiful and unique glass bottles, perfect for those who like to enhance their creation just a dash more!  They have all the same characteristics as our Amber bottles, although are slightly stronger in UV protection for your oils and products! With a narrow neck for precise mess-free pouring! These bottles are particularly great for light-sensitive essential oils and carriers. As they will protect the substance from light damage by absorbing the UV rays it's hit with. We love these jars for holding and protecting our essential and sensitive products! This helps prolong their shelf life too! -High Quality -Beautiful Appearance -Trusted Resource -Recommended for Aromatherapy use
