Important Notice:
- Inventory Status: Please check the inventory status on the product page. Our system displays real-time stock for our Munich and Arlington warehouses. If an item is out of stock in these locations, it will be marked as "Pre-order". You can still place an order for these items.
- Pre-order Fulfillment: For "Pre-order" items, we arrange the most efficient logistics solution to ensure you receive your goods as quickly as possible. Your package may be shipped directly from our Shenzhen warehouse. Alternatively, as part of our standard restocking process, we may transport the goods to our Munich or Arlington warehouse first (typically taking 5-10 business days) before dispatching them to you.
- Split Shipments: If your order contains both in-stock and Pre-order items, we will prioritize shipping the in-stock items from the local warehouse immediately. The remaining Pre-order items will be sent to you in a separate shipment once they are ready.
3. International Warehouse
Our products are stored in our Munich, Arlington, and Shenzhen warehouses to provide more flexible logistics solutions tailored to different regions and customer needs. On each product's description page, we indicate the specific warehouse location to help you better plan your purchase and delivery schedule.
