When a new collection drop takes place, item availability is limited. No products will be re-produced and if an item is sold out, it may become available again as part of a return drop. Return drops take place shortly after the release of a collection and are announced via Instagram and newsletter.
Only RAWS are restocked when they are sold out. You can recognise this by the tag "Back Soon" and the time of the restocks is communicated on Instagram as well as via newsletter.
