The Borg Warner factory made the ABS plastic pellets that they supplied to the Wrexham, Whales factory to make legit LEGO® bricks. In the 1960's, LEGO® gave the Borg Warner plant 2x4 brick molds so they could make test bricks to test their plastic pellets. The factory workers took the test bricks home and gave them to their kids and neighbors kids to play with. Factory workers made solid color test bricks along with some odd non-traditional LEGO® color test bricks. They even got a little crazy and made marbled bricks by mixing multiple colors together. The majority of the Grangemouth bricks found in the wild today came from local children's toy collections and are well used. Our Grangemouth bricks all have play wear on them including scratches, dents and dings. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eFor a more details about the Grangemouth bricks, read \u003ca href=\"https:\/\/atlbrick.com\/blogs\/news\/grangemouth-lego%C2%AE-bricks\" title=\"Grangemouth LEGO Bricks\"\u003eour blog post on the subject!\u003c\/a\u003e\u003c\/p\u003e","brand":"LEGO®","offers":[{"title":"Default Title","offer_id":42929407950915,"sku":null,"price":399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2372\/6695\/files\/41F228E6-7BBB-4177-9EC8-04D6C8EC4332.png?v=1770086909","url":"https:\/\/atlbrick.com\/products\/yellow-white-marbled-1970s-grangemouth-test-2x4-lego%c2%ae-brick","provider":"United Brick Co®","version":"1.0","type":"link"}
