Lippy Links is a set of combined silicone rings that connects your matching lipstick and lip liner.
The large ring is 1.5cm or 0.59 inches. If the bottom of your lipstick measures this then Lippy Links will fit your lipstick. The lip liner is a standard slim size.
It is aimed at Kylie Cosmetics so will fit any brands that are of this size. It's not a one size fits all it is a one size fits many.
Each Lippy Links box has 5 rings so will connect a total of 10 matching lipstick and lip liner combos.
