For broken dishes, the buyer must include an image showing the broken dish(es) with the original packaging, a dated note in the image. To qualify for a refund for grain, the buyer must contact the seller within 7 days of receiving their products.

For bags not including an injection port, dated images of the bag will be requested. For substrate refunds, the buyer must show a defect with the bag or picture of visible contamination before opening. If the buyer uses any of their products in any way after receiving it, this voids the warranty and disqualifies the buyer for any opportunity of a refund.
