Anti Slug Flanges 20 Pcs Plastic Plant Protection Product Description: A set of 20 anti-slug collars is an effective and ecological method of protecting plants from pests. Made of high-quality plastic, the rings are weather-resistant, durable and reusable. With a flexible design and a 45° angled edge, they form a physical barrier that effectively keeps slugs at bay without the use of chemicals. Not only do the flanges protect the plants, but they also support sparing watering – they trap water around the plant, preventing it from spilling to the sides. It is the perfect solution for gardeners who want to take care of their vegetables, flowers and herbs with care and precision.
