Because our products are research materials and may be temperature sensitive, all sales are final once an order has shipped. We do not accept returns or exchanges.
If your order arrives damaged, incorrect, or with a shipping issue, contact us within 48 hours of delivery with your order number and clear photos of the package and items. We will review the claim and, when appropriate, arrange a replacement or store credit.
Orders that are delayed, left unattended after delivery, or stored improperly after arrival are not eligible for replacement or refund.
