Returns & refunds

Last updated: June 2026

Because these are research materials, returns are limited. Here's how we handle issues.

Damaged or incorrect orders

If your order arrives damaged, or you received an incorrect item, contact us within 7 days of delivery with your order number and photos. We will make it right with a replacement or refund.

Non-returnable items

For safety and integrity reasons, opened or used research materials cannot be returned. This protects the quality and traceability of every product we ship.

Refunds

Approved refunds are issued to the original payment method. Please allow a few business days for the refund to appear after it is processed.
