i first encountered these keys for squeezing oil paint out of metal paint tubes in a college painting class. turns out, you can also use them to squeeze every last drop out of your toothpaste, lotion, and tomato paste tubes. not sure about you, but i find it super satisfying to finish my products, down to the last crumb.
bonus rec: this Marvis toothpaste absolutely slaps. it’s crisp and minty, and you can’t beat that graphic design. if you’re in Chicago, Merz and Eataly both carry it in various flavors.
