The finger slits are pre-cut just a half an inch so that you can customize them to the perfect fit for you. Just take a pair of sharp scissors and snip a tiny bit (like 1mm!) at a time until it's comfortable for you.
Remember that the bands s-t-r-e-t-c-h. Don't overdo it! You don't want a big gaping hole!
HandBand Pro® Original
See the finger slits on each side of the grip? Think of them like you do training wheels on a bike. Just like training wheels are not necessary for the bike to fully function, the finger slits do not need to be used to gain the full benefits of HandBand Pro®.
Because they are so different from anything you may have used before, it's sometimes helpful to use one finger slit on each band (with either your pinkie or pointer finger) until you are comfortable with them and they feel like second nature.
Just use one finger on each band. If you put two fingers through, you'll create a large gap between the band and your hand and that just won't do.
HandBand Pro® OMEGA
You may need to customize both the inner and outer bands.
