The limited edition KKW X Kylie Cosmetics lip kits with Kim debuted in April.

Kylie told WWD that ‘there is room for the both of us in the makeup world,’ adding We respect when we launch new things.’

She noted that they ‘make sure there isn’t overlap.’

Kylie released her first three items on November 30, 2015; they were the Dolce K, Candy K and True Brown K Lip Kits.

The $29 kits – which have a lip liner and a coordinating lipstick – sold out in under 30 seconds on kyliecosmetics.com; WWD reported that they only had 5,000 kits in each color – so 15,000 units total.

There was however a mini restock of the three lips kits on Christmas Even in 2015.
