This lovely instrument can open up to a whopping 4" (11cm). Specially designed to allow incremental opening and holding, the handle has a locking mechanism to ensure full control.
The fantastic lips on this design are curved at the end to ensure it doesn't pop out whilst in use. Although small and very light this device is so easy to use. Can be used solo or by a top that can just sit back and watch.
This is one of our office favourites!
