THIS EXTRA STEP THAT WE DO COSTS MORE, BUT INSURES THAT YOUR ITEM ARRIVES INTACT. ALSO THE CONTAINER KEEPS YOUR PRODUCT FRESH. All chemicals are sold as 1 lb = 1 quantity unless otherwise stated. Please do not order aluminum and perchlorate on the same order, you MUST order chlorates and aluminums on separate orders since we must ship them separately.
