The designer's work covers goods, packaging and book covers, and Sanby notes many of the illustrations use nostalgic colors. There are five designs. Unlike the artist eric's [acrylic stand stamp](https://stationerytimes.com/guides/sanby-eric-acrylic-stand-stamp/), this one has the ink inside. ## Which designs are there? **Retro Post, Deepsea Post, Mazuiya Confectionery, Ghost Post and Tabikuma.** Sanby says each stamp's ink color is matched to its design. The Retro Post name matches the designer's own goods brand, per Sanby. ![The 30 by 48.5 mm stand stamp inside its 32 by 50 mm package outline](https://stationerytimes.com/images/sanby-ob1-acrylic-stand-stamp-package.svg?v=eed9601b) *The stamp and its package at 1 mm = 4.2 px. Original illustration made for this guide. © Stationery Times.* ## How big is it? **The stamp is 30 × 30 × 48.5 mm and the face is 21 mm square.** The package is 32 × 32 × 50 mm. | | Value | |---|---| | Stamp | 30 × 30 × 48.5 mm | | Package | 32 × 32 × 50 mm | | Face | 21 × 21 mm | | Ink | built in | | Tax-included price | 1,320 yen (about US$8.35) | Prices are Japanese prices at 158 yen to the dollar. ## How does it differ from the eric stand stamp? **It carries its own ink, and the face is smaller.** The eric stand stamp has a 30 mm face and needs a pad; the ob1 has a 21 mm face and no pad. If you want a self-inked artist stamp without the stand, see the [eric absorbent stamps](https://stationerytimes.com/guides/sanby-eric-absorbent-stamp/). ## How should you handle it? **Keep it away from small children, avoid strong force and keep it out of the heat.** Sanby's notes say the stand can break under strong force, that small parts can cause choking if swallowed, and that it should not be left near fire or in a hot place such as a car. ## Who is ob1? **A graphic designer and illustrator whose concept is retro and cute, per Sanby.** The designer works on goods, packaging and book covers with illustrations that have a story, and Sanby notes the colors are often nostalgic. The designer also published a book of color-scheme ideas and runs a personal goods brand called Retro Post. Sanby also makes ob1 sealing wax sets and single sealing stamps; see our [sealing wax sets guide](https://stationerytimes.com/guides/sanby-sealing-wax-set-eric-ob1/). ## How does it compare with other Sanby artist stamps? **It is the pricier of the two stand stamps.** Sanby lists the ob1 at 1,320 yen (about US$8.35) against 1,100 yen (about US$6.96) for an eric stand stamp, but the eric one needs a separate pad, which Sanby sells at 1,760 yen (about US$11.14). The ob1 face is 21 mm square against 30 mm. The [ANZ stamps](https://stationerytimes.com/guides/sanby-anz-riceball-island-stamp/) are plain rubber stamps on blocks at 825 to 935 yen, also with no ink. ## Where is it made, and what does it cost? **Sanby's page doesn't give a country of manufacture.** Sanby is a Japanese company founded in 1921 with its head office in Osaka.
