Back when I started PE’ing I looked everywhere for "Homedics TheraP Magnetic Wrist Wrap". I’m not even sure if you can buy it on line anywhere. A google search will produce results of vendors but if you look closely all of them are "Out of Stock".
I solved the problem by buying the $9 McDavid Jumpers Knee Brace . I’ve seen them at several sporting goods stores, Kmart and a number of pharmacies.
There a foam support inside the brace that was easily removed. Then I cut the elastic to the desired length. Nothing to it! You may be tempted to trim the width of the brace to match the with of the Velcro. (you’ll understand if you get one). Don’t do it! You can trim some width but I’d leave 1/4" on either side of the Velcro. Reason being, as time passes the elastic stretches and the hard plastic Velcro teeth will eventually creep over the layer it’s attaching to and really irritates the skin. So leave a little playing room.
Be warned that I do NOT recommend wearing this for extended periods without constant monitoring of circulation. Even with minimal tension, gland chilling and numbness can occur in a short period of time. I’m speaking from experience and I promise that will scare the shit out of you. Just to drive the point home, obstructed circulation can cause permanent damage. End Disclaimer.
