(TAISEI Co., Ltd.) in Higashiosaka, Osaka. The Swing Letter carries a message of congratulations or thanks cut into the paper by laser, so light passes through the words and the colored inside reflects softly on the surface under it. We read the maker's English page on November 4, 2026. The maker says it will swing when placed on a flat surface and gently pushed, which is why it suggests keeping it out as a decoration after the occasion. For more small desk pieces, see our [best desk accessories](https://stationerytimes.com/guides/best-desk-accessories/). The brand's name, Sikigu, is the maker's own word for paper-tools, and the Swing Letter is one of 25 product pages on its site, alongside pads, boxes, envelopes, trays and clocks. That context matters for expectations: this is a design-led paper object more than a conventional stationery card, which is why the maker talks about light, motion and decoration before it talks about writing a message. ## What are the size and contents? **110 × 55 mm, paper, with an envelope.** That is all the maker's spec lists. | Spec | Maker says | |---|---| | Size | W110 × H55 mm, fold in half | | Material | Paper | | Contents | With envelope | | Variations | Congratulation, Thank you, Happy Birthday, NicoNico; Bouquet, Thank you, Present, Cake | | Price (UK, November 4, 2026) | £2.99 (about US$3.95), $ band | The listing is ambiguous about whether 110 × 55 mm is the card folded or opened. At 110 mm wide it is a little wider than a bank card (85.6 × 54 mm, drawn below); the height is almost the same. ![A Swing Letter at 110 by 55 mm with a bank card of 85.6 by 54 mm laid over it at the same scale](https://stationerytimes.com/images/sikigu-swing-letter-bank-card-comparison.svg?v=8103096d) *The listed 110 × 55 mm size against a bank card at the same scale. Original illustration made for this guide. © Stationery Times.* ## Which variations and colors are there? **Eight named variations on the maker's page, each with a colored inside.** They are Congratulation, Thank you, Happy Birthday and NicoNico in one row, and Bouquet, Thank you, Present and Cake in another. The maker's photo shows a Thank you card with a blue inside and a NicoNico card with an orange one; we sampled those two tints and did not sample the rest. A UK retailer lists additional variations, so the range may be wider than the maker's page. ## Who is the Swing Letter for? **It suits someone who wants to send a very small card that is meant to be kept out, because it sways on a flat surface and measures 110 × 55 mm.** The maker pitches it for celebrations and casual greetings. It is not a place for a long message: the card is smaller than most notecards. The maker does not say whether the inside takes ink, so we did not tag it with a use from our list; check it before relying on it for writing. ## What does it cost, and where is it made? **It sits in our $ band (under $5).** The Journal Shop in the UK listed one at £2.99 (about US$3.95) on November 4, 2026. Prices change, and we did not check other sellers. The maker does not state a country of manufacture on the page we read, and it names no paper weight, so we cannot say how stiff the card feels. A UK retailer's page describes the same laser-cut lettering and colored inside and says the card sways when nudged, which matches the maker.

The maker lists W110 × H55 mm with the note fold in half. It does not say whether that is the folded or the opened size, so measure yours. ### Does it come with an envelope? Yes. The maker's contents line reads with envelope. ### Why does the card sway? Per the maker, when it is placed on a flat surface and gently pushed it swings. It does not explain the shape that allows this, and we have not tested it. ### What are the laser-cut words for? They carry the message, such as Congratulation or Thank you. The maker says the carved words let light through and reflect it, and the colored inside reflects gently on some surfaces. ### Which variations are there? The maker lists Congratulation, Thank you, Happy Birthday and NicoNico, and a second row of Bouquet, Thank you, Present and Cake. A UK retailer lists more, so the range may be wider than the maker's page. ### Can I write inside it? The maker does not say. Because the inside is colored, ink may not show on it; try a paint pen or write on a separate note. ### How much does it cost? The Journal Shop in the UK listed a Swing Letter at £2.99 (about US$3.95) on November 4, 2026. Prices change, and we did not check other sellers. ## Sources - [Taisei Shiki (maker): Swing Letter, size, material, contents and variations (read November 4, 2026)](https://taisei-shiki.jp/product/swing-letter/?lang=en) - [Taisei Shiki (maker): Sikigu home page and product list (read November 4, 2026)](https://taisei-shiki.jp/?lang=en) - [The Journal Shop (UK retailer): Sikigu Swing Letter, price in GBP and variant list (read November 4, 2026)](https://www.thejournalshop.com/products/sikigu-swing-letter-greeting-card-with-envelope)
