Party At Santa's Workshop. A Christmas Clay sprinkle mix. Comes in a 5 gram bag, not a jar. Works great for arts, crafts, resin, slime, shaker charms, 3D nail art, snowglobe tumbler cups. I did test these in my 16oz Starbucks and they did fit but you will need to do your own testing in your own cup. Please conduct your own testing before using in final project.
