Our slim line rubber collar is more subtle that our heavy duty rubber collar since it uses only 1 steel d-ring for an attachment. Strong enough for serious bondage use but discreet for outside wear. Closes by means of a steel non-locking rear buckle. Built to have the durability and strength of collars twice its price. Rubber is easy to clean compared to leather so no worries about being messy.
This is a really good collar. I mainly use to on my fiancée when I want to put her on a leash. Although, its nothing fancy, I would consider it a good trainer collar.
