【Authentic Product】BackJoy Relief Grip - Black This popular item supports your posture just by sitting on it. Recommended for those concerned about lower back strain. BackJoy Relief Grip (Black) Naturally positions the pelvis and supports correct posture. Recommended for remote work and office work. Used a few times, but I am selling it because I can no longer use it due to a department transfer at work. There are no scratches or fading, and it is in very clean condition. #BackJoy #BackJoy #ReliefGrip #Pelvis #LowerBackPain #CorrectionCushion #PostureImprovement #PelvicSupport #LowerBackPainRelief #DeskWork #RemoteWork
