Instructions
Selecting and using it.
How to select
Measure circumference 4 cm from the distal end of the residual limb. Choose the size closest to the measurement. If the measurement falls between two sizes, round down. Then assess fit and feel with the user.
How to use
Roll on from the distal end without trapping air, avoid stretching the textile over the brim, and clean daily with mild soap and water.
