THE BEST WAY TO PROTECT YOUR FLOOR AND YOUR OUTDOOR PLAY AREA NO MORE STAINS: These plant feet provide proper drainage for all your favorite outdoor plants. The feet keep your pots elevated, which means water can drain through your pot without staining your patio slabs, decking, or tiles. Perfect for displaying plants on your patio, porch, or deck. It's also important to elevate your pots so they can ventilate, which helps improve the health of your plants. INVISIBLE DISCREET DESIGN: Since these plant stands are 1 cm high, they will lift your pots off the ground, but will not detract from your beautiful flowers. Once attached to the bottom of your pot, you won't be able to see them. For extra height, you can stack two on top of each other. ROUND RISER FUNCTION: The round riser directs water away from the bottom of the pool more efficiently than other square risers on the market. Allow rain and water to flow freely under your pots and preserve your patio, deck, and pots. BE SURE TO CLEAN the bottom of the pot before attaching the feet to them.
