These buttons are in great shape and measure 7/8 inch. T are 6 altogether. They are backmarked "E. Marthinsen Tonsberg" Have no idea!! Buyer to pay S&H of 1.75. Ins. is optional - please remember that when paying invoices. Some of you are insuring $5 items - that seems a waste of money to me, but I will do as you pay! I will gladly combine auctions ending within 48 hours of each other to help you save on shipping. Please do not pay on multiple purchases until I have invoiced you . I try to wait to the end of the day when all listings are done. If you overpay insurance and shipping before I invoice you, I won't be responsible to return it. Paypal actually takes a fee based on what you pay so if I returned you full overpayment, I would come out on the short end. If you buy just one item , you may go ahead and pay what is listed. When you are finished buying, please request an invoice for total. Otherwise I will invoice you at the end of a days sales or the next morning. +++++++++++I DON'T COMBINE SHIPPING ON ITEMS ENDING MORE THAN 48 HOURS APART - PLEASE DON'T ASK ME TO. IT MESSES UP MY RECORDS. Full shipping will be charged for late paid items even if you are buying more items later. I am not responsible for lost or damaged packages once mailed. I save USPS Receipt showing date sent to your zip code. I do have good feedback and package carefully .=============PLEASE NOTE: DO NOT BID IF YOU WON'T PAY!!!!!!!=============== I have had a couple non-paying bidders lately. That costs money. Even if I get my final value fee back, I lose .75 minimum in listing costs!! I have been putting all my auctions on one day so that you don't have to worry about combining. I admit I am behind on leaving feedback, but please be patient - I will get to it! I VERY MUCH APPRECIATE ALL OF YOU REPEAT CUSTOMERS. YOU MAKE THIS A PLEASURE!!! Most of the buttons I am listing are from a large estate collection I bought a few weeks ago in Muskegon, MI that weighed 160 pounds! It has taken me a long time to sort into general types. I plan on listing some bigger lots soon since t are just so many!! T will be some wonderful ones and some more commmon, but many to please! Keep checking back with me for new ones listed. I also still have some wonderful ones from some smaller estate lots that will also be listed. Please look closely at the pictures and ask questions before bidding as ALL SALES ARE FINAL . I describe as best I can and try to show good pictures. I WOULD ONLY GIVE A REFUND IF I GROSSLY MISREPRESENTED AN ITEM AND THAT IS HARD TO DO WITH PICTURES! I definitely Prefer Paypal , (AND FULLY EXPECT TO RECEIVE YOUR PAYPAL PAYMENT WITHIN 48 HOURS OF CLOSE OF AUCTION) but will accept Money orders and Cashier's checks if mailed quickly . I need to RECEIVE it within 7 days. I ask for payment quickly because I have had several people wait a week or two until I have to remind them to pay. I also need you to fill out your invoice so I know how you are paying. This helps to keep me from getting confused because of current listings. I will start leaving non-paying bidder reports on items that go over 7 days. PLEASE DON'T BID IF YOU CAN'T PAY!!! Thanks so much for looking. Be sure to check out my other button auctions and even my business items.
