If you love having the back door open in summer but hate the infestation of flies this door screen is perfect it fits easily to most single and sliding doors using self adhesive tape no drilling or fixing required the fine nylon mesh curtain panels keep out all sorts of nasties securing shut with strong magnets but opening at a gentle push of the body or hand the pretty butterfly design makes a lovely addition to summer and when not in use it folds neatly away until next year
