In our shop, you can find two types of products:
• Unique pieces – unique items that are in stock and ready to ship.
• Made-to-order items – products made after your order is placed.
Please note that although some items are available immediately, many are made individually for each customer. Production time for made-to-order items is typically 2–4 business days, depending on order volume.
We ask for your understanding and consideration when placing an order.
Please avoid ordering multiple items with the intention of keeping only one.
This practice leads to unnecessary production and contradicts our commitment to sustainability.
We value responsible consumption and aim to reduce waste by only producing what is needed.
Thank you for supporting conscious, small-scale production.
