My swatches in the last photo are done on Hobonichi's older 52 gsm grid notebook made of Tomoegawa Tomoe River Paper. Unsure what type of paper the company used in their product photos. Ink colours may appear differently depending on the screen, the type of paper, lighting, and the method of swatching.

Product details:

• Fountain pen ink (some colours have glitter)
• Glass bottle
• Bottle size: 30mL
  
• Country of origin: South Korea
