Firstly this is not a medical device!
It is strongly recommended that you do your own research on pulley injuries and inquire with a doctor about treatment, I am not a doctor and based the device on recommended rehab programs described in the following papers:

Please measure your injured finger using the following guide: https://tinyurl.com/mu2u9eyd
Or find some dental floss or string, wrap it around the bottom section of the finger, roughly at the same location as your A2 Pulley and measure the length of the wrapped string on a ruler.
Also, please measure the distance between the knuckle and the first joint on the affected finger.
Every purchase comes with 4 splints, one of the exact provided measurements, and 3 more variations to make sure you get the exact right fit and to compensate for any measurement error.
If you have any questions please message me anytime.

This was developed after a serious A2 Pulley injury on the ring finger during a climb and it was recommended by medical professionals to obtain a pulley-protection splint to aid in recovery.
As none were available in Australia and sourcing internationally seemed expensive we then researched and developed a splint based on any finger's dimensions.
After trialing with others and receiving positive reviews in recovery I decided others might benefit from the development, especially climbers within Australia.
The medical image above shows the location of the A2 Pulley, when a rupture occurs the pulley bowstrings away from the proximal, this disrupts healing and can cause discomfort. The Pulley Protection Split will support the pulley back into its normal position and minimize the bowstringing, as can be seen in the following picture:
The most effective bowstringing reduction is achieved when the splint is placed right next to the proximal joint, between the middle and proximal bone.
