These handcrafted bowls retain their actual shape and size. These variations are the characteristics of the all-natural shell. Untouched by chemicals and polished with coconut oil, the rawness only adds to the charm of these beauties. These Coconut shells are lightweight, durable, and easy to maintain. Why Coconut? The coconut tree is a great and sustainable resource. Every part of the tree can be used the leaves, the fruit meat, the water, the milk, the oil, the husk, and lastly the shell. Care: Hand wash with regular soap water (do not soak for long period) and wipe it dry immediately. To increase the lifespan, you can rub coconut oil every once in a while. Do not use it for extremely hot food or heating in the microwave oven, as the extreme temperature can cause the bowls to crack. Do not refrigerate or use in the dishwasher. Afterlife: If it breaks, you can put it into the compost, it is as good as food waste.
