The classic retail size — Boston rounds, syrup and spray bottles at 120 ml
Four ounces — 120 millilitres — is the classic mid-size of retail packaging: big enough for syrups, tonics, lotions and room sprays, small enough to stay shelf-friendly. We produce the 120 ml format in amber, flint and black glass across Boston rounds, syrup bottles and spray bottles, with DIN and GPI neck options.
As the manufacturer we supply 4 oz bottles wholesale with matched caps, droppers and pumps from one source — and if your product needs its own shape, we develop a custom mould from your drawing, from first glass sample to series production.
