{"product_id":"ball-pen-cacao-grey-hazy-pink","title":"Ball Pen Cacao Grey × Hazy Pink","description":"\u003cp\u003e\u003cspan\u003eBallpoint pens in the past used \"sticky\" ink, but Anterique's oil-based ballpoint pens use \"ultra-low-viscosity ink\" (Mach ball ink). Ultra-low-viscosity is ink that is \"smooth\" and easy-flowing like salad oil. When using \"smooth\" ink, an ordinary pen tip will have ink leakage, so it must be combined with an ultra-precisely processed pen tip. Anterique ballpoint pens use a pen tip with a built-in spring to precisely control the flow of ink for a very crisp, non-smudging, ultra-fine .5mm line. This is the secret to smooth writing! Made in Japan.\u003c\/span\u003e\u003c\/p\u003e","brand":"BlueberryHugs_Tableware","offers":[{"title":"Default Title","offer_id":50535085342898,"sku":"A272189","price":9.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/8073\/7970\/files\/Screenshot2026-09-24at1.57.20PM.png?v=1790283446","url":"https:\/\/bluberryhugs-tableware.com\/products\/ball-pen-cacao-grey-hazy-pink","provider":"BlueberryHugs_Tableware","version":"1.0","type":"link"}
