One replacement Instalock™. Note: please choose the Instalock™ corresponding to the kit that you’ve purchased, as they are not interchangeable.
Pictured first is the Instalock™ for our AeroThumb. The one with the flat back is the Instalock™ for our TGuard Classic.
Please note: Instalocks™ are included in all thumb sucking treatment kits (not required for FingerGuards™).
