My DD went to an 11 year old spa sleepover and came home with a shower caddy with nail polish, a big cup with a straw that had some saying on it like “you do you” and this headband - 3 Pieces Hair Headband Headband to Wash Face for Women Makeup Spa Headband, Microfiber Bowtie Shower Headband for Women and Girls (Pink, Blue, White)

The headband was the biggest hit, the mom sent pictures of them wearing them with face masks. My kid still wears hers to sleep in. It was super cute.
