These 4 oz amber glass spray bottles are built for essential oils, homemade hand sanitizers, and DIY face sprays that need UV light protection. Solid amber glass blocks ultraviolet rays to preserve the potency of light-sensitive liquids, while odorless, BPA-free, and lead-free construction keeps your mixtures clean and safe. A fine mist nozzle delivers a smooth, even spray for witch hazel, air freshener, deodorant, household cleaner, and hair spray. Leak-proof performance ensures contents stay sealed during storage and transit. The 2-pack includes two extra black fine mist sprayers, one funnel, one dropper, and four labels—giving you everything needed to refill, label, and maintain your bottles easily. Refillable and reusable for long-term cost savings.
