Thank you for looking \(◡̈)/♥︎ I bought this last year due to moving, and have one set left in storage at home. I think it's a must-have for families with small children ★ Retail price: ¥4,980 per set ■ Door pinch guard [Hasamamosu] The danger is not on the doorknob side, but on the hinge side. Because the hinge side works on the principle of leverage, if a finger gets caught, there is a risk of fracture or amputation. Hasamamosu is a product that can prevent finger-pinching accidents on the hinge side. ■ Advantages of Hasamamosu Easy to peel off, so it's safe for rental properties! Transparent, so it's inconspicuous! Widely adopted in nursery schools! ■ Patented Product It is patented as a "finger-pinching prevention device," so you can use it with confidence.
