Kreinik Balger Blending Filament mixed new and used Variety of colors Vintage?

Description

Lot of spools as shown.
The top row appear to be new to me with the tag still wrapped around.
The bottom row I assume have had some used although most of them still look pretty full to me.
Estate sale find. I think some may be vintage.
I am not familiar with these so ask a question if there is something I should look for.
My items come from many different places and I cannot say how or where items may have been stored (pets, smoke, etc.).
I only ship to the United States.
I will only ship to the address on file with Ebay.  If you have a new address, please change it before you buy.
I try to give an accurate description of items and take pictures to show condition. I am not an expert on these items.
I will combine shipping on items when possible.
In an effort to be green and to save money, I also recycle boxes, bags, envelopes, and packing materials when I can.
Feel free to email me with any questions or concerns.
Please contact me if there are any problems with your item.
I try to be as complete as possible when listing, but there may be a time I miss something.
