The Tesselation container system consists of airtight glass vessels for storing dry foods or liquids. Plastic packaging associated with food consumption is a major contributor to plastic waste. One way to avoid plastic waste is to reuse packaging. Bringing own packaging to zero waste shops is one alternative, filling canvas bags with dry foods or liquids into glass containers. The shape of the jars is stackable and easy to nest. In addition, tesselation jars feature an ergonomic grip of 8 cm in diameter. Their spout allows to accurately pour liquids and dry foods. A silicone seals the jar airtight to transport liquids.
