Waterproof sticker Highly effective when used with security cameras or dummy cameras! Security measures that you can implement simply by sticking them in a conspicuous place at home, work, parking lot, etc.! Instant purchase OK. I also list on other auctions, so there is a possibility of sudden removal. Thank you for your understanding. Also, I have many other items for sale, and if you purchase multiple items, I may be able to offer a discount on shipping depending on the combination. Please consider. If you have any unclear points, please contact me.
