These items are Gilbert Erector Set Part BL Washer, Cadmium. Washers are in good condition. The Washers have an OD of 3/8" and an ID of about 5/16". Will Sell the whole batch for $13.50 or make an offer..Please to look closely at pictures, because in the end they are your best way to determine condition.  All items in pictures are turned over/around in place for the reverse/side view of the item. I will combine orders. The shipping costs are showing up a little high as I haven't quite got it together on figuring out postage accurately on/in the format now used (haven't sold in awhile). It may cost less to mail this item than listed. I will send Items as cheaply as possible and refund excess postage if it is over .50 cents in any case. Most items will include insurance costs in shipping.
