It’s a practical accessory for commuters, road-trippers, and anyone who prefers a single large bottle instead of multiple smaller cups. If you frequently carry tall or wide containers and your vehicle’s cup well is a standard round shape without raised lips, this insert will greatly reduce spills and movement. Measure your bottle diameter and cup-well depth before ordering to ensure compatibility; consider SEVEN SPARTA’s upgraded options for containers wider than 3.8 inches or unusually obstructed cup holders.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What bottle sizes fit this expander?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Designed for most 32–40oz bottles with diameters about 3.4\"–3.8\"; measure your bottle before ordering.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will it fit in any car cup holder?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It fits many round cup wells but not holders deeper than 1.8\", square-shaped, or with raised lips or covers.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"SEVEN SPARTA","offers":[{"title":"Default Title","offer_id":55168101974359,"sku":"B087F5NLTT","price":46.25,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/seven-sparta-front-view-installed_b4aa8cfb-981e-484a-a0c7-234c0625eea8.jpg?v=1790396513","url":"https:\/\/britishgarage.co.uk\/products\/seven-sparta-car-cup-holder-expander-for-32-40oz-bottles-deep-base-rubber-grip","provider":"British Garage","version":"1.0","type":"link"}
