IFMC. IFMEC Balance Guard Lumbar Belt Lumbar Supporter Made in Japan Thank you for looking. I feel like my blood circulation has improved. I myself am using the same item. The size is L. It does not come with a bag or box, but it is unused. I gave it to my father as a gift last year, but he returned it without using it. Would anyone be interested? It can be used by crossing the straps over the shoulders.
