Our SB 1000 soy blend container wax has a very smooth surface and adheres well to glass containers. The blend is made of 60% soy wax and a 40% blend of paraffin, UV and an enhancing additive. Compared to 100% Soy Wax, SB 1000 soy blend container wax has superior cold & warm fragrance throw and ideal burn quality. Use HTP wicks for best burn performance. This wax puts off a stronger smell. The scent lasts longer and smells fresh for quite some time. The reason for this is because they burn at a much slower rate and the fragrance is released at a slower rate as well. Which in return will give you a fresher smelling candle for longer. This item comes with 4 pieces of 1lb wax blocks.
