I have hundreds of the platters from hard drives. ****I will ship to anywhere within the 48 states*** If you do not know below is a hard drive platter It is similar in size to a CD but it is much shinier and it is much more durable(I shot one with a 450 FPS airsoft Pistol and it just put a dent in it) they are used in arts and crafts and sculpting but I came up with the idea to hang them around the coop instead of CD's to create glares and reflection to keep birds of prey and other predators away from your flock easily here is one in my hand so you can see it in comparison This is how thick they are (varying) This is just with lights on in the room no lights are shined directly onto the platters. these are twenty of them spread out on the table just to show them all to you here is one hanging I am sure you are wondering where I got all of these, well with a lot of work we have been taking apart hundreds of hard drives for the motherboards inside them. I have almost a thousand of them lying around now and I was thinking of how to use them so they don't go to waste and I came up with this. If you decide that you want a larger quantity you can pm me and we can work something out. I accept PayPal and will ship out next business day on almost all occasions.
