Our egg cup is made of oak or beech wood, which gives them a specific structure and color. They’re crafted for us in a small wooden workshop in the Czech Republic, beautifully smooth and finished with pine oil. Just in time for your breakfast soft-boiled egg. Wash carefully by hand with warm water and mild soap, don’t put it in the dishwasher. Don’t let your egg cup soak in large amounts of water for long periods of time. Dry with a tea towel. From time to time, you can rub in a small amount of oil (any type will do), using a soft cloth or a paper towel to make it last longer.
