Thank you for viewing. This is a collector's edition 1670 ink with a sea theme, featuring green ink in a square bottle. - Brand: J. HERBIN - Product Name: 1670 Ink - Color: Emerald Green (with glitter) - Bottle Design: Square bottle - Edition: Collector's Edition - Style: Sea-themed design - Accessories: Instruction manual I purchased this and tested it to check the color, but I haven't used it since. The ink contains gold glitter, so if you're using a fountain pen, I recommend using it with consideration for the nib size. It should be easy to use with dip pens, glass pens, etc. I hope to pass it on to someone who can use it.
