Firefly said glass packaging was essential to reflect the premium nature of the product, with director, Marcus Waley-Cohen adding: "Beatson Clark were our preferred glass manufacturer as we felt they gave added value to their service.
"A stock bottle was selected from Beatson Clark's range, and slight adjustments were made to the design of the bottle by their design team to accommodate our final packaging needs."
Firefly Tonics are available from all branches of Harvey Nichols in the UK, and various health and deli stores across London, priced between £1.49 - £1.99.
