They’re black and they hold the wheels on the truck. I really enjoy how they do their job no questions asked. Now have you ever had just plain butter and toast? Well. it is time to step your game up, next time you’re making toast with butter like normal. then take a little bit of cinnamon and dust over top of the toast. When completed take a small amount of granulated sugar and pretend to be "Salt Bae” and sprinkle that sugary goodness all over that warm bread. Enjoy
