Example Input: It can only fit the very small cups and with all the pressure the drink shoots back up on my daughter. Quality is good but design is not made for my little one.

Example Input: After reading and watching the other reviews I decided to order this hair and I hate that I did. This hair is on the level of some low equality Beaty supply pack hair and to be honest I've had some better pack hair then this " virgin hair". I had a blunt cut straight bob and it kept flipping up like a kick stand. I li tried it curled and the curls dropped within a hour or so. These other reviewers are either lying, never had good quality hair or got a better batch than me. Idk!!LADIES ORDER AT YOUR OWN RISK
