Thank you for viewing. This is a DAIWA Crystia TG-R. Some have been used, some haven't, but I have too many sinkers, so I'm organizing them. I take them with me every time I go fishing, so some, as shown in the third photo, have been rubbed against each other. Recently, I've been carefully applying a graphene ceramic coating to all of my rod tips and equipment with a micro cloth and brush. I did it to everything while I was at it. It took a tremendous amount of time... Even if they get dirty, they can be easily wiped clean, and I think they repel dirt and water well. 1.0: 2 pieces 1.5: 2 pieces 2.0: 2 pieces 2.5: 2 pieces 3.0: 2 pieces 3.5: 2 pieces 4.0: 2 pieces 5.0: 2 pieces 6.0: 2 pieces 7.5: 2 pieces There are 20 pieces in total.
