Raymay Fuji, founded in Japan in 1890, is a staple brand in Japanese stationery. Their DaVinci rings systems launched in the 1990's, and as soon as we saw these we knew Dear Whoever needed to stock them!
All the DaVinci inserts are printed on cream 64gsm Tomoe River Paper, for high-quality inserts for your rings, but a little more durable than the more commonly used 52gsm TRP.
Some more specifications:
all inserts are undated, with space to easily fill in your own dates
