Notice:  Update on USA Tariff Policy and Shipping Arrangements

Due to recent changes in USA tariff regulations, all shipments to the United States will now be routed through a third country to help our customers avoid high import duties. As a result, delivery times will be slightly extended. Standard Airmail: Estimated delay of approximately 10 days, DHL/UPS Express: Estimated delay of approximately 5 days. We appreciate your understanding and patience as we work to minimize the impact of these changes.
