The Ter Steege planter from the Cera-mix collection is made of synthetic material, making it sturdy and lightweight. The use of recycled material makes this planter a sustainable choice. The structure of the planter is smooth and the finish is matt, giving it a modern and subtle look. This model is specially designed for outdoor use and is frost resistant, allowing the planter to remain outside during cold periods without being damaged. There is a drainage hole in the base, which efficiently removes excess water, helping to maintain the condition of the plants.
