Peace, mercy, and blessings of God be upon you. An almost new optical device, I used it for only 4 months, and it was used carefully and not tampered with. When I first bought it, I bought it new from Al-Saqr for Sports. Only serious buyers should contact. The optical device is known for reducing weight and tightening skin and sagging. Reason for selling: Praise be to God, my weight has decreased and I no longer need it.
