One Big Styrofoam Box. Widely used in the commercial fish Industry as a lightweight container for Transporting fish from the field to the Hatchery.Please be aware: Although Styrofoam boxes do not weigh much individually, they present problems when they enter the UPS shipping system. The actual size of the box trips the UPS Dimensional weight threshold, increasing the shipping cost by 2,3, or maybe 4 times what the gross weight of the shipment might otherwise imply. Please contact the Store (800-940-3833) or by email (sales@4fishstuff.com) to get the most accurate and cost effective means of shipping. Thank You........ FTFFA Web Sales
