All Jean Dubost products come with a lifetime guarantee, so the quality is undeniable. The Nature line takes this guarantee of excellence one step further in its design and sustainable manufacturing practises. The blade is 100-percent recyclable and the handle work is made of corn starch, so it's 100-percent recyclable, compostable and biodegradable. Even the label is printed with vegetable ink. For every tree this company takes from its forest to use for a box to hold their cutlery, they plant a new one in its place. This is definitely a gift you can feel good about buying.
