The company that blends and packages it is <strong>Warren Distribution</strong>, which merged with Highline Aftermarket in 2020 to become <strong>Highline Warren</strong>. That name appears on the shipping cases far more often than it appears in forum threads.</p> <p>The reason this question gets 390 searches a month with almost no editorial answer is that the shelf is designed to hide exactly this. A private label exists so that the retailer, not the factory, owns the customer relationship. The factory is happy to stay invisible.</p>
