    Made in USA.

    Rather than collect shells, rocks and other natural objects, consider taking photos or drawing a sketch instead and let the objects stay where they are. The Leave No Trace principle of "Leave What You Find" ensures the next visitor will experience the same joy of discovery you have and permits valuable, sometimes imperceptible, materials (such as the minerals in shells) to stay in their ecosystem for future plants and animals to use.
