4 oz Amber Glass Bottles

About

The 4 oz amber glass bottle is a go-to size for brands packaging anything that shouldn't sit in direct light. Every bottle here is a classic Boston round shape with a 22-400 neck finish, available in true amber or a frosted amber finish for a softer, matte look. Need a different capacity? The full amber glass bottles collection runs from 0.5 oz up to 32 oz. Built for Light-Sensitive Formulas Amber glass blocks out UV rays that break down oils, extracts, and active ingredients over time. That's why it's the standard choice for essential oils, tinctures, serums, and anything with a shelf life you actually want to protect. A 4 oz bottle is also the right size for a lot of formulas — big enough to feel like a real product, small enough that customers won't feel like they're overpaying for empty space. If you're working with a different neck finish or bottle shape, our Boston round and specialty bottle catalog covers the rest of the lineup. A Reliable Choice for Small-Batch and Private Label Producers Whether you're bottling your first batch or scaling up an existing line, the 4 oz size hits a sweet spot for testing new SKUs without committing to a huge minimum order. It's also a popular sample and travel size for brands that sell a larger container as their main product. The 22-400 finish is compatible with droppers, pumps, sprayers, and standard caps, so switching closures later doesn't mean switching bottles. Why Glass Glass doesn't leach chemicals into your product, doesn't hold onto odors between fills, and doesn't degrade under UV exposure the way some plastics do. It's also fully recyclable, which matters more and more to the customers buying what you make. We supply bottles only — caps and closures are sold separately, so you can pick exactly the finish and function your product needs instead of getting stuck with whatever came in the box.
