2 oz Black UV Glass Boston Round Bottle with Black Lid

The iconic Boston Round silhouette, reimagined in genuine black UV glass - built for formulations that deserve real protection. Highlights True UV-filtering black glass (not painted) blocks 99%+ of the light spectrum responsible for oxidizing plant actives, essential oils, and tinctures. Leak-resistant 20-400 screw cap included - smooth black PP lid that seals tight for oils, liquid serums, and water-based formulas. Classic Boston Round shape - the industry-standard bottle profile trusted by herbalists and cosmetic brands worldwide. 2 oz (60 ml) volume ideal for face oils, tinctures, bath blends, and retail sample sets. Pack of 12 for everyday use; Pack of 24 for production, gifting, and professional batch filling. There is a reason the Boston Round bottle has been the go-to vessel for chemists, herbalists, and cosmetic formulators for over a century. Now in genuine black UV-filtering glass, this 2 oz Boston Round adds full-spectrum light blocking built into the glass itself - not a coating. At 60 ml, the 2 oz size is perfectly calibrated for daily facial oils and serums, herbal tinctures and liquid extracts, hair and scalp treatment blends, and retail-ready sample bottles for indie beauty brands. The smooth exterior is label-ready and photographs beautifully. How to Use Use a small funnel for precise liquid filling. Fill to 5–8 mm below the neck. Tighten lid fully. Store at room temperature away from heat. Hand-wash or rinse between refills.
