storage slide frame cup half sphere

This cup is designed to fit into the storage cup slide frames also available in this store.  As a small hemispheric cup it won't hold much but I'm envisioning it being more of a dome that can be lit from the inside by a small LED bulb.  

Remember, the top of this cup that slides into the frame is emulating an Activia yogurt container, so if you can repurpose a used yogurt cup you can definitely save some money.
