Large Acorn Caps - 7 Count

This is an assorted pack of 7 large acorn caps from Burr Oak trees and Sawtooth Oak tree. Four of the large acorn caps have a fringe, and three do not have a fringe. These caps are about the size of a US quarter. Isopods and springtails enjoy acorn caps and they make excellent ground scatter in a terrarium. These will also release tannins in a blackwater aquarium. Product Details: Source Location: USA.
