[Supervised by a Physical Therapist] Arm Holder Arm Sling Arm Support Arm Sling Triangular Bandage Size: One Size Product Use/How to Use: Post-surgery support, fracture Target Age: Adult Color: Black About this product: [Supervised by a current physical therapist x Ergonomic Design] Our arm holder was developed under the supervision of a current physical therapist, a "professional of human anatomy." We pursued both a "natural fit" and "comfortable wear," thoroughly researching the shape of the arm and wrist, muscle movements, and even daily life movements. Utilizing the specialized knowledge and experience cultivated in the field, we have adopted a support structure that evenly distributes the weight of the entire arm. It is designed to be safe for those who need to wear it for long periods due to rehabilitation, fractures, or sprains. It is for both left and right arms and is unisex, fitting a wide range of body types. It will be shipped via Yu-Packet Post.
