Every GKV piece is made from a unique fabric, vintage textile or old garment, so care can vary from bag to bag.
Always check the product title and description to see what your bag is made from and follow the recommended care for that material.
For example, velvet prefers gentle handling and minimal washing, while wool should be kept away from heat and preferably spot cleaned or dry cleaned.
When in doubt, treat your GKV piece gently — no harsh washing, tumble drying or excessive heat.
