Recycled PET
Sourced from single-use bottles. Tough, water-repellent, and easy to clean. Used in lunch bag outer fabric; repurposes waste into durable goods and encourages more sustainable habits.
Cardboard Packaging
Unbleached, uncoated cardboard that is recyclable and home-compostable. Orders are shipped in recycled boxes and materials when possible to minimize waste.
Charcoal
Active charcoal filters water naturally, with no plastic involved. Follows a traditional Japanese technique; producers harvest branches only (roots are preserved) on a 5-year regrowth cycle. Wood is sourced locally.
Cork
Sustainably sourced, renewable, biodegradable, and 100% natural. Harvested without harming the tree's survival. An excellent insulator, used for vacuum flasks and bottles.
Glass
Borosilicate glass — lightweight, strong, and temperature-resistant (oven, microwave, and freezer safe). Resistant to thermal shock and chemicals; lead- and BPA-free. Lasts a lifetime and is fully recyclable.
Stainless Steel
304-grade (18/8) stainless steel for durability and corrosion resistance. Fully recyclable, lasts a lifetime, and improves with age and patina.
Wood Composite
Recycled and PEFC-sourced wood mixed with polypropylene or TPR. Highly durable, ages well, and increases the bio-based polymer content of the product.
Plastic
Used sparingly and responsibly (polypropylene, Tritan, POM). BPA-, BPS-, and phthalate-free, and fully recyclable. The company's position: the issue is single-use waste, not plastic itself, when it is designed for durability.
