Thank you for viewing. These are Ebi Nuts stored in a factory. I don't think there are 1,000 pieces, but they are unused. They have been stored for a long time, so there may be some dullness or dirt on the plating. They are offered at a bargain price. These are, at best, used but unused items. Please do not purchase if you are looking for something in new condition. No returns accepted. Shipping will be done by taking them out of the original box and putting them in a bag. Thank you for your understanding and consideration. Ebi Nuts NSK-8M manufactured by Lobtex Co., Ltd.
