The Clear Plastic Push-Up Pop Containers come in the perfect dimensions, the cylindrical chamber measuring 3-3/16 inch high x 1-7/8 inch diameter. The push-up stem measures 3-3/4 inch long x 3/8 inch diameter. Capacity 3.0 ounces. A great way to prepare, serve and eat dessert. The stem of this plastic cup gets joined to a disk that you push from beneath to raise the food as you eat it. The push-pop container comes disassembled, but attaching the parts is a cinch. First you insert the stem in the disk. Then you push those connected parts, stem first, inside the cup. A stand can help you prepare a bunch of cream desserts at once. When you've finished filling the cups, put on their lids (supplied in the package), and freeze the dessert in a blast chiller.
