How long does 3D-printed jewelry last?
There's no fixed "expiry date" for our jewelry — with proper care, it's wearable for years. That said, PLA behaves differently from metal: it's more sensitive to high heat, direct sunlight, and impact. Kept protected, it holds its shape and color beautifully.
What are the bags made of?
Each bag is made from Italian deadstock leather — surplus rescued from the luxury fashion industry — and handmade in our Berlin studio. Every design uses a different, distinct leather, so each one feels and ages a little differently. Small variations in color, texture and surface are natural and make every piece unique.
Shopper – Cavallino (calf hair)
Mini Bag – Varnished leather
Double Bag – Nappa lambskin
Please ask us for the circularity certificate of your material.
How should I care for my bag?
Care instructions are included with every bag. As a general rule: store your bag away from direct sunlight and heat. Please avoid overfilling.
Cavallino / calf hair (Shopper)
Keep it dry: water can mark the hair and flatten the texture. If it gets wet, let it air-dry naturally, away from heat, then brush it back into place.
Varnished leather (Mini Bag)
The glossy surface wipes clean easily with a soft, dry or slightly damp cloth. Avoid contact with rough surfaces. Store it wrapped, so the surface doesn't stick to other materials in warm conditions.
Nappa lambskin (Double Bag)
Nappa is exceptionally soft, which also makes it sensitive. Handle with clean hands, keep it away from moisture, and wipe gently with a dry cloth. An occasional light leather conditioner keeps it supple. Avoid friction against rough surfaces to protect the soft grain.
