Purchased through a Makuake crowdfunding campaign. It arrived on November 4th, and I immediately installed it in my entryway, but unfortunately, the height didn't work due to the steps in my home, so I'm reluctantly putting it up for sale. Photos ① to ⑤ are of the actual product. The main unit and the instruction manual are included. The main feature is that it locks with a single step on the pedal, and it unlocks by simply pushing the door. For more details, search for "踏むだけで固定。ドアを「ポン」と押して解除｜スムーズに使えるドアストッパー" (Locks with a step. Unlocks by pushing the door｜Smooth door stopper) to find information on the website. Thank you.
