Rodger, I buy 5" labels from OBC Northwest in Canby, Oregon. You can also get shorter labels. They ship just about anywhere. I'm assuming those labels are Macore. I've used pencil for 20+ years on these labels. As far as I can tell, they have always used the same supplier and the quality has improved, specifically, the uv resistance. I find labels written in pencil from ten years ago that are still quite legible. Macore is in Lafayette, Oregon, if I remember correctly, and I would suggest contacting them directly. A box of 1,000 labels from OBC runs about 22-24 dollars American, but you should be able to find a supplier near you if they won't sell directly to nurseries. It's the shipping that costs...
