My swatches were done on Tomoegawa Tomoe River Paper (Hobonichi's older notebook). Not sure what kind of paper was used in the comany's product photos.

NOTES: 

• Ink colours may appear differently depending on your screen, the type of paper, lighting, and the method of swatching.
• Once inks are decanted into sample vials, the colour may vary due to oxidation and evaporation.
