{"product_id":"koiguchi-t-shirt","title":"Koiguchi T-Shirt","description":"The mouth of a katana's scabbard is called the koiguchi — the carp's mouth — and the sword sits in it friction-tight, seated so it cannot slip free. Before anything can happen, the thumb presses the guard and eases the blade loose by exactly its own width. The gesture has a name, kōiguchi wo kiru, and everyone who has watched a samurai film knows it by heart even if they never learned the word: the close-up, the click, the inch of steel taking the light — the moment when nothing has happened yet and everything has already been decided. This design is that moment cut to a single silhouette, one hand, one thumb, one line of light at the carp's mouth. It pairs with our 鯉口切り calligraphy piece: the word, and now the deed.","brand":"Gaijin Smash","offers":[{"title":"Black \/ XS","offer_id":47881729605737,"sku":"koiguchi-unisex-tshirt-xs-black","price":35.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ S","offer_id":47881729638505,"sku":"koiguchi-unisex-tshirt-s-black","price":35.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ M","offer_id":47881729671273,"sku":"koiguchi-unisex-tshirt-m-black","price":35.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ L","offer_id":47881729704041,"sku":"koiguchi-unisex-tshirt-l-black","price":35.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ XL","offer_id":47881729736809,"sku":"koiguchi-unisex-tshirt-xl-black","price":35.0,"currency_code":"USD","in_stock":true},{"title":"White \/ XS","offer_id":47881729769577,"sku":"koiguchi-unisex-tshirt-xs-white","price":35.0,"currency_code":"USD","in_stock":true},{"title":"White \/ S","offer_id":47881729802345,"sku":"koiguchi-unisex-tshirt-s-white","price":35.0,"currency_code":"USD","in_stock":true},{"title":"White \/ M","offer_id":47881729835113,"sku":"koiguchi-unisex-tshirt-m-white","price":35.0,"currency_code":"USD","in_stock":true},{"title":"White \/ L","offer_id":47881729867881,"sku":"koiguchi-unisex-tshirt-l-white","price":35.0,"currency_code":"USD","in_stock":true},{"title":"White \/ XL","offer_id":47881729900649,"sku":"koiguchi-unisex-tshirt-xl-white","price":35.0,"currency_code":"USD","in_stock":true},{"title":"Red \/ XS","offer_id":47881729933417,"sku":"koiguchi-unisex-tshirt-xs-red","price":35.0,"currency_code":"USD","in_stock":true},{"title":"Red \/ S","offer_id":47881729966185,"sku":"koiguchi-unisex-tshirt-s-red","price":35.0,"currency_code":"USD","in_stock":true},{"title":"Red \/ M","offer_id":47881729998953,"sku":"koiguchi-unisex-tshirt-m-red","price":35.0,"currency_code":"USD","in_stock":true},{"title":"Red \/ L","offer_id":47881730031721,"sku":"koiguchi-unisex-tshirt-l-red","price":35.0,"currency_code":"USD","in_stock":true},{"title":"Red \/ XL","offer_id":47881730064489,"sku":"koiguchi-unisex-tshirt-xl-red","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/4760\/2025\/files\/tshirt-white-front-desktop_171fc572-89f7-4aa0-a7b8-1677fbc7a8ed.webp?v=1786273489","url":"https:\/\/8n1yma-er.myshopify.com\/products\/koiguchi-t-shirt","provider":"Gaijin Smash","version":"1.0","type":"link"}
