{"product_id":"sea-grip-chalk","title":"Sea Grip Chalk","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe same clean, ocean-derived chalk as the liquid formula, in the classic powder format climbers already trust.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eSea Grip's magnesium carbonate is drawn from mineral-rich seawater and concentrated through solar evaporation rather than traditional mining — a genuinely different sourcing process, not just marketing language, and one that results in a single-ingredient chalk with nothing else mixed in. No rosin, no silica, no fillers bulking out the bag. Every 275g purchase also removes a pound of at-risk ocean plastic through the brand's Oceanworks™ partnership, so the sustainability angle carries through the whole Sea Grip line, not just the liquid and refill formats.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eResponsibly sourced, non-mined magnesium carbonate\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSeawater-derived, solar-evaporated\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRosin-free, silica-free, no fillers\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSingle-ingredient formula\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEvery bag sold removes 1 lb of ocean plastic (Oceanworks™ partnership)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSize: 275 g (9.7 oz)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMaterial(s): magnesium carbonate (seawater-derived)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Midnight Lightning Climbing","offers":[{"title":"275g \/ Chunky","offer_id":54825174860119,"sku":"psr1788126982876","price":10.82,"currency_code":"GBP","in_stock":true},{"title":"275g \/ Powder","offer_id":54825174892887,"sku":"nrg1788126982877","price":11.36,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1025\/7517\/8071\/files\/sea-grip-chalk_1.webp?v=1788126987","url":"https:\/\/www.briarandbay.shop\/products\/sea-grip-chalk","provider":"My Store","version":"1.0","type":"link"}
