Col-O-Ring Testing Book
Very useful ink testing book for my fountain pen ink swatches. Price is very compatible too. Wish I could order more. Excellent product!
I've been using Col-O-Ring for years with my fountain pen ink and I've loved it. I've gone through about 4 books so far and onto my 5th, thanks to Noteworthy Stationery. Fast delivery, packaged well, great pricing... I'm hooked! Thanks Noteworthy! xo
These little cards are perfect for swatching colours, watercolour or acrylic!!! Love Love Love
