Shipping Update

We are now seeing improvements in our shipping times. However, things are not yet back to normal and there are still some delays occurring. We will provide updates as the situation changes.

Our normal shipping time averages 1 - 2 weeks. Due to the pandemic, shipments may sometimes take an additional 2 – 4 weeks to arrive, depending on the source country of your order. Shipments from the United Kingdom and Canada are generally quicker than from other countries.
