A set of bins made for smaller solderless breadboards, of which the standard sizes for them are usually around 54-56.5mm wide, around 82mm long and 9mm thick. If your breadboard is that size or smaller it should fit just fine as most breadboards follow the same standard sizes. There are 3 bins included with one that has text on the side, one with text on the front and one with text on three sides, so no labels are even needed. Happy Printing!
