This is a wheelchair luggage holder. It attaches to the frame by looping it as shown in the second photo and adjusting it. The size is as shown in the photos. The 13cm in the 7th photo is the height of the back of the luggage platform, and the 5.5cm in the 8th photo is the height of the front. The sides have a height that follows the connection of 5.5cm and 13cm from front to back. It is three-dimensional, so luggage is less likely to fall out. An acrylic plate is inside and can be removed. I don't think there are any major stains, but there are some scratches and dirt from a few uses, so please refrain from purchasing if you are sensitive to this. Shipping will be in simple packaging. #Wheelchair #LuggagePlatform #Luggage #SuctionPlatform #RespiratorPlatform #Tilt #Reclining #SeatingSupport #PostureSupport #KisakuKobo #Assistance #Wheelchair #ChildrenWithDisabilities #Buggy #KawamuraCycle #Miki #MatsunagaSeisakusho #Matsunaga #Nissin #Nissin #Nursing
