Gutto Window Stopper Color: Brown Set of 6 Purchased new on Rakuten. Retail price: 800 yen Unopened, unused. Many manufacturers release window stoppers as safety measures for children and babies, but Gutto's window stoppers have sold over 40,000 units and have received high ratings. They offer a quality and attention to detail that sets them apart from other companies. They have narrowed down the selection to one factory from among several that primarily manufacture child locks and safety locks, choosing the one best suited for preventing "falls and dropping accidents" and most dedicated to "easy locking and safety measures." They place orders only with this factory. They are constantly improving the product after its release, incorporating customer reviews to refine the color variations and improve the quality of the tape, to deliver a product of even more satisfying quality. 【How to Use】To lock, simply raise both sides. To open and close as usual, leave both sides down. It's a compact type, so it won't get in the way. *Use multiple stoppers for increased strength. Size Length: 7.4cm Width: 8.9cm Thickness: 0.7~0.9cm
