We offer free shipping globally on all of our products. We aim to reduce our environmental impact by reducing the number of shipments our products have before arriving to our customers. Rather than shipping to multiple warehouses globally, and increasing the carbon footprint of each product, we ship with minimal packaging, and often direclty from our suppliers.

Our products may be shipped either directly by Effentii, or from our global distrutors and suppliers. Any orders made may be delivered in separate packages, and a single order may be delivered in multiple parts.

All orders are processed within 5 working days, and delivery times vary depending on the shipping method chosen. For standard international shipping, delivery times range from 14-28 days from the date the packages have been dispatched to the shipping company.
