Price is per blank. The blanks are 1.5"+ square by 6" long. The "Quad Lava" line of blanks feature 4 colors of alumilite. Where those colors interact the color possibilities are crazy. This is the same material as all the other Lava Lamp and Lava Explosion blanks.
These blanks are made in small batches here in the USA, so some variations in color from batch to batch should be expected. In addition, the patterns in the blank will definitely vary by blank. We will attempt to ship blanks from the same batch when possible. You will receive a random blank not the blank shown in the photo.
Made in the USA, with acrylic resins.
