Each pack includes rectangular plastic flower planters measuring L16.6 x W7 x H5.9 inches—large enough to support a variety of projects, from herbs and flowers to succulents, ferns, cactus, and more. Made of high-quality, recyclable plastic, these durable planters are lightweight yet sturdy, resistant to sun, rain, and snow without fading, and easy to clean thanks to their smooth surface. An attached drainage tray promotes healthy root growth by preventing overwatering, while the built-in water inlets at the bottom allow for convenient watering without making a mess on tables or windowsills.
