All brands aim to send out standard items within two working days of your order being received, however please note that there have been unprecedented delays due to COVID. To allow for creation time, made-to-order pieces will be posted within 10-14 business days, dependent on the respective brand.

To our friends outside of Australia and New Zealand, please note that we do not currently ship worldwide due to a range of factors, though mainly due to the package delays brought about by the COVID pandemic.
