I got these off my magnolia tree in my backyard last year. I have boiled them and dried them making them ready to use. They are great additions to tanks for a variety of reasons. Great for shrimp tanks in particular because they like to eat the biofilm that develops on the surfaces. I use them in all my tanks with no issues but always beware adding anything foreign to your tank. 50 for $10 Located in Fairfax, VA
