Product Description Robin Joy Riggsbee origami packs from Aitoh feature reproductions of original pencil drawings by this well known artist and designer– they’re not just origami, but beautiful little decorative papers. The Robin Joy Riggsbee series that we carry are 15cm square. The packaging lists them 6, but the metric is more accurate than the standard. These packages contain 5 patterns and 20 total sheets, so you get 4 of each.
