This is the Richell screen door stopper R. I bought two sets of the same item, and I've been using one set for several years. This one is new, unopened, and I haven't used it. It's the type that attaches with adhesive tape. A gap of 3.5mm or more is needed between the screen door and the glass door. Would you like to try it out at a low price? (⁠ ⁠ꈍ⁠ᴗ⁠ꈍ⁠) * I also have corner guards for sale. I can combine shipping. * I have a cat. I will be careful when shipping, but cat hair may get mixed in. #Richell #RichellBabyGuardScreenDoorStopperR
