Product Sustainability

We use premium vegetable tanned Italian leather certified by the Pelle al Vegetale Consortium. Durable and full of character, it develops a warm, personalized patina over time.

This sustainable tanning process uses natural plant-based materials, reducing chemical waste and environmental impact while honoring traditional Italian craftsmanship.

We craft our products thoughtfully, producing only what’s needed to reduce waste. Occasionally, this means a favorite item may be temporarily unavailable. Thank you for supporting mindful and responsible production.

Processing & Shipping

Due to the nature of handcrafted products, each journal is carefully crafted and inspected by hand, which requires time. Please allow 2 to 3 weeks for processing before shipping.

We do not accept cancellations once production has begun, but if you have any issues with your order, please contact us and we’ll do our best to assist.
