I love them, just for carrying around like the villagers do! I just think it's cute. It reminds me of in New Leaf when all the dream addresses would have an outfit and a coffee from Brewster's for you to carry around and take cute pictures in while you were in their dream.
I'll also probably eventually use them for decorating.
I’ve used the used fountain fireworks as decoration. I haven’t really been able to decorate with any of the rest. I’ve tried to, but the cotton candy and other decorations look weird placed. The tea items are sooooo small. Little drinks for tiny ants.
I like the new cotton candy and boba tea items. I just hate how some of boba teas look in the game. I wish the tea was a little bigger so it didnt look so small. I know that they are consumables but they should know players want to use them as decorations too. The good news is that the cotton candy is good in a stall and I can finally have a reason to use the cotton candy maker as a decoration.
As for raffle items, I have gotten some prizes and stored them away or used them in the very moment and then they disappeared.
As for the items in the stores, I have never bought any of the items other than the art stuff.
