FAST & SECURE SHIPPING 📦
I use fast, reliable, and monitored logistical routes to your region. Once your package reaches your country, it is handed over to a local subsidiary of Cainiao Global Express or a major national carrier, such as Evri or Royal Mail for the UK, Colissimo for France, Poste Italiane for Italy, Correos for Spain, or Bpost for Belgium 🌍
I typically dispatch items within 2 business days for products shipped from my warehouse in France and within 5 business days for products shipped from my Hong Kong warehouse. Every package comes with a tracking number, with estimated delivery times ranging from 10 to 20 days, depending on your location. However, most packages arrive within 7 to 10 days ⚡
Q: How long does shipping take? ⏱️
A: Most packages arrive within 7-10 days, with full tracking available. The Cainiao Global Express logistics network ensures reliable transit times, unlike standard shipping services that may take much longer.
Q: What is the journey of a package? 🗺️
A: Every package follows a highly optimized and secure logistics path to ensure fast and reliable delivery. It begins at my warehouse in Hong Kong, where it is prepared for shipment before being transferred to Cainiao Global Express' logistics hub in Mainland China, marking the official start of the shipping process. From there, the package moves through Cainiao's high-efficiency logistics network, ensuring continuous monitoring and rapid transit to its destination country. Once it arrives, it is either handed over to a local Cainiao subsidiary or entrusted to a major national carrier for smooth final delivery. This process guarantees secure, fast, and well-tracked shipping, providing the same level of efficiency as major global retailers.
