I found the slushee cups in the Target dollar section so unfortunately you can’t order online BUT I linked the info to make it easier to find it at yours and an alternative from Amazon in case yours doesn’t have them As well as all of the other supplies of course ☀️ Would make super cute end of year classroom gifts, party favors OR swap out the gift tag to make it a birthday gift You can even add in an alcoholic beverage or energy drink to gift this for adults!
