Ink Circles is still open, shipping orders placed through the site and orders to your favorite shops and distributors. That said, shipping times for printed charts seem to be taking a little longer than normal, particularly those headed out of the US. Fortunately you probably have something else to work on while you wait. ;-)
Three new charts were released for May 2020 and are now available through stores everywhere, and three new ones at the end of June. I've also been adding Digital Delivery options for many older charts, including splitting up a few larger charts. To see the full list of PDF charts, look under Digital Delivery in the Catalog menu.
