Questions, answered
What does "non-toxic" mean at Ziruma?
We build our kitchenware around materials with a long track record in contact with food: FSC-certified acacia wood, borosilicate glass, platinum silicone and surgical-grade stainless steel. Why non-toxic matters
Why don't you use mineral oil on your cutting boards?
Mineral oil is petroleum-derived. Our boards are conditioned with food-safe beeswax, flaxseed oil and lemon oil instead.
Are your glass containers oven and freezer safe?
Yes. The borosilicate glass containers are oven and freezer safe. Check each product page for lid care details.
How do I care for wooden boards and utensils?
Hand wash with warm water and mild soap, dry right away and re-oil from time to time. Full care guide
Is shipping free? What about returns?
Yes, shipping and returns are free. See Shipping & Returns
