@rhodeswrites very kindly tested out various fountain and calligraphy ink on our journals to check the paper. We were already very pleased with our paper as none of the pens we have used have bled through and were delighted that her review supported our views.
Here is a copy of the test which @rhodeswrites did using an Ink Pot journal:
She said she tested out diamine, scribblers and paper chase generic cartridges and a Pilot Parallel pen. All lovely - no bleed through to the other side apart from the Pilot a tiny bit but it is heavy ink lay down. She said it is "Fab paper"!
