Sold as a pack of 30. These teaching aids are about the size and shape of a typical queen cell. Glue them to your favorite cell cup. This can easily be done by mounting your cups on a bar then adding a ring of glue to the cell and carefully placing it on a cup. Consider doing just a handful at a time. Jostling the bar can cause the freshly glued cells to topple. Gorilla Glue works very well. Made of PLA plastic.
