"Copper-infused Vase: The Secret to Prolonging Flower Lifespan"

TL;DR
Glasgow-based design company POTR Pots has created the LetterBox Vase, inspired by a centuries-old technique of using copper to keep flowers fresh.

The initiative aims to reduce premature flower wastage and is available in three pastel colors.
