Pick one -   Pull through Side mount Pull Through Kaleidoscope discs.  These mount on the side instead of the center, making it easy to center each layer of color. Fits inside a vertical column soap mold that is 2.5"x3.5".   I do not have the mold but did use one from Wholesale Supply Plus, the mold is called a rectangle regular column silicone soap mold 2009.  Each acrylic disc is cut with a laser.  1/4" Thick.  There is paper on both sides that needs to be peeled off.  You get flowers, kaleidoscope, Geometrics, artisan soap.  These do not come with rods.  This is for only one Disc, to make your own.  I do have a YouTube channel Wild Plantanica that will show how to use these. RODS ARE SOLD SEPARATELY, since everyone used different heights of Molds.
