The serum size — droppers, Boston rounds and sprays at 30 ml
Thirty millilitres — one ounce — is the standard size of serums, essential oils, tinctures and beard oils: one of the most ordered bottles we make. The 30 ml format runs in amber, flint and black glass as dropper bottles, Boston rounds and fine-mist sprays, with glass pipettes calibrated to the bottle.
Wholesale quantities ship with closures matched on the same order, and in-house decoration — frosting, printing, hot stamping — turns the 30 ml workhorse into your brand’s bottle.
