The Mold Exchange: Refresh Your Studio

At Castaway Market, we believe every mold has a story and every artist deserves a fresh canvas. Our signature Mold Exchange program is designed to help you rotate your inventory and discover new inspiration without the overhead.

How it Works: Bring in your pre-loved ceramic plaster molds and receive instant store credit to use toward anything in the market—from brand-new Duncan designs to unique artisan commissions.

The Exchange Guidelines: To ensure a curated and manageable selection for our community, we observe the following monthly limits per customer:

Small Molds (finished design under 8"): Up to 15 molds per month.
Large Molds (finished design over 8"): 1 mold per month.
The "No Duplicates" Rule: To keep our inventory diverse for all artists, we do not accept duplicate molds of the same design in a single exchange.
Condition: Molds must be in usable, castable condition.
Finality: All exchange transactions are final.

The Collector’s "Wish List": Looking for something specific? Check our Curated Desires board. If you bring in a mold that is currently being "wished for" by another artist, you'll help us fulfill a community request while clearing your own shelf space.

Cast. Create. Collect. — Turn your "Castaways" into your next great creation.
