Anti-Snail Collars Hoops Snail Protection Set of 12 Pieces Product Description: A set of 12 anti-slug collars is an effective, safe and ecological way to protect plants in the garden. Snails can destroy flower beds and young vegetables in one night, so a physical barrier in the form of protective collars is one of the most effective solutions. Collars create a tight, mechanical barrier that prevents pests from accessing plants while not affecting their natural growth. This allows your vegetables, herbs and ornamental plants to thrive healthily and without hindrance.
