These are the Firefly Portable Recovery Devices. This is a brand new package that has not been opened. This package contains 1 pair of straps (two straps total).
Each Firefly device delivers 30 hours of recovery treatment (suggested recovery time of 1-4 hours based on training intensity).
Firefly delivers electrical pulses to stimulate the peroneal nerve in your leg, triggering muscle contractions that boost blood flow.
This enhanced circulation speeds up the body's natural recovery process, helping to reduce muscle soreness and get you back to your active routine quicker.
