Cupcake mold
It would be very tiring if we counted every time little crumbles and dirt found their way into our cup holders. We could never reach a number since this happens so often. This is a problem because we want our holders clean.
Instead of vacuuming the crumbs every day, there is something you have in your kitchen that could be very helpful; cupcake molds. Put them in the cup holders and you will notice the difference. There will be no more crumbs, you can enjoy your coffee and you will not have to clean every single day.
