In Japan a seal, or hanko, signs forms, and carrying the ink saves a separate red pad. Tsukineko describes the design as one you want to pick up, like a small gadget. Our [Kodomo no Kao Techo Hanko-bu stamp guide](https://stationerytimes.com/guides/kodomo-no-kao-techo-hanko-bu-stamp/) covers a planner stamp for a related job. ## What are its dimensions? **72 × 72 × 17 mm, with a 32 mm round pad.** The case holds a seal up to 12 mm across and 61 mm long. | | Value | |---|---| | Case | 72 × 72 × 17 mm | | Ink pad | 32 mm round | | Largest seal | 12 mm across, 61 mm long, or oval | | Package | 86 × 21 × 135 mm | | Types | IN-R01 to IN-R06 | | List price before tax | 1,380 yen (about US$8.73) | Prices are Japanese list prices at 158 yen to the dollar. The seal is not included. ![An Inos R case outline with its round ink pad drawn inside it to scale](https://stationerytimes.com/images/tsukineko-inos-r-seal-case-ink-pad-face.svg?v=d1d590c8) *The 72 × 72 mm case and its 32 mm round pad at 1 mm = 2.6 px. Original illustration made for this guide. © Stationery Times.* ## How does it ink and print? **A large pad takes ink easily, and the print dries fast.** Tsukineko says the larger pad makes inking easy and that the print is crisp. On plain paper it dries in about 3 seconds, so there is little risk of transfer. It lists plain, woodfree, Kent and inkjet papers, cardboard and washi. ## Why is it called Inos R? **R stands for round.** Tsukineko makes two shapes: S, the slim one, and R, the round one, in the same series. The protective pad keeps the seal from making noise. A similar compact idea for stamps is the [Midori Paintable rotating date stamp](https://stationerytimes.com/guides/midori-paintable-rotating-date-stamp/), which carries its own pad. ## What are the features? **Three, per Tsukineko.** The seal comes out easily and the case stays clean; a protective pad stops the seal making noise in the case; and a large ink pad makes inking easy and suits carrying. Tsukineko says the print dries fast, so there is no worry about color transfer on plain or woodfree paper. ## How does it compare with other Tsukineko office pads? **It is the portable one.** The [Stampnic Eco](https://stationerytimes.com/guides/tsukineko-stampnic-eco-ink-pad/) is a desk pad with a 90 × 55 mm face, while Inos R is 72 × 72 mm and carries one seal. It is not a craft pad: Tsukineko lists Inos with its red seal ink and office supplies. ## Where is it made, and what does it cost? **Tsukineko's page doesn't give a country of manufacture.** The company history lists a Yoshikawa, Saitama factory and a US subsidiary in Redmond, Washington, and says the Inos R and S seal cases were announced in 2011. At 1,380 yen (about US$8.73) before tax the case is in our $$ band ($5–20). ## Frequently asked questions ### What does Inos R hold?
