リングノート - A5 - 両面今日も地下深くで、せっせと石炭運び。 ここは、働くカエルたちの職場「カエル炭坑」。 表紙では、ヘッドランプをつけたカエルの炭坑夫たちが、石炭を掘ったりトロッコを押したりとお仕事中。 煤で汚れた作業着、古いランタン、トロッコ、坑道など、昔の炭坑を思わせる風景を昭和レトロな雰囲気で仕上げました。 そして裏表紙では……やっぱり休憩中。 仕事道具を置いて、腰を下ろしてひと休み。マグカップを片手にくつろいだり、寝転んだりと、表紙とは違うカエルたちの姿が楽しめます。 一生懸命働いているようで、ちょっとサボる。 そんなカエルたちの日常を、表紙と裏表紙で一つの物語のように楽しめる「働くカエルの業務日誌」シリーズです。 炭坑・鉱山などの古い産業風景が好きな方、昭和レトロやカエル好きの方、少し変わったノートをお探しの方にもおすすめです。 ※画像はデザインイメージです。実際の商品では、印刷位置や色味が多少異なる場合があります。 この商品はpixivFACTORYで作られた商品です。サンプル画像は完成イメージのため、実物と異なる場合があります。

English Description
SHOWA RETRO FROG COAL MINE | WORK LOG NOTEBOOK Deep underground, the frogs are hard at work again today. Welcome to the Kaeru Coal Mine, a fictional workplace run by a crew of hardworking — and occasionally not-so-hardworking — frogs. On the front cover, frog miners wearing headlamps are busy digging for coal and pushing mine carts through the tunnels. Soot-covered work clothes, old lanterns, coal carts, and dark underground passages create a nostalgic industrial scene inspired by old Japanese coal mines. But turn the notebook over... On the back cover, the frogs are taking a break — again. Their tools have been put aside. Some sit down to rest, some relax with mugs in their hands, and others simply stretch out and make themselves comfortable. They work hard... but they also know when to take it easy. The two covers tell a small story: Front — frogs hard at work. Back — frogs on a well-earned break. This notebook is part of the Working Frogs Work Log series, featuring hardworking frogs and their slightly laid-back lives in nostalgic Japanese workplaces. Perfect for anyone who loves frogs, Showa-retro design, old industrial scenery, coal mines, mining history, or unusual Japanese stationery with a little humor.
