How do I tell my friend the nails she made me kinda suck? And I want a refund?

My friend made me some press ons for Halloween and I couldn't wear them because of just how bad they were. I thought they were super super cute but they were really expensive for them being her first ever set for someone other than herself. I feel super bad but I don't know how to ask her for like some money back because it wasn't my money but my boyfriends, and he hated them...

He said he wasn't happy with them and that he wanted me to look cute with my nails but instead I looked like some cheap wh0r3....

I just need some advice because I absolutely love this girl and wanna support her but I'm just not happy with the outcome, any advice helps. Thanks guys!
