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 ⚡

EASY RETURNS 🔄

If you need to make a return, there's no need to ship the item all the way back to Asia. I make returns easy by accepting them directly at my warehouse in Marseille, France. Feel free to reach out to me — I'm here to make the process as smooth as possible 📬

TRANSPARENCY AND EXCELLENCE ✨

All items are presented accurately in photos and descriptions. If you have any issues with your purchase, please contact me. Your satisfaction is my top priority 💯
