Convenient 2-Piece Set: This set includes two planters, each 20.3 cm in diameter. The planters are lightweight and easy to handle. The indoor/outdoor dimensions are suitable for almost all small to medium-sized houseplants, as well as herb and spice gardens. The planters are ideal for orchids, cacti, succulents, aloe vera, basil, flowers, peace lilies, air plants, and snake plants. Easy Drainage Holes & Removable Tray: Excess water drains through the two drainage holes to prevent overwatering and flooding. The trays collect any overflowing water for easy cleaning. It is recommended to place a layer of plant material at the bottom of the planter.
