Nice lot of bubbles

Reid Barnett
Good product but be aware of shipping

This product works well in my formulations and I would highly recommend it. However, be aware of shipping it in the colder months as it will freeze and the alter the product's functionality. Thawing afterwards will leave solid matter that may partly redissolve after many months in a warm environment with constant shaking. The more solid matter you have, the more challenges you will have in your formulations, as it can change your final product
