I’ve found myself having many leftover batteries after events that I don’t feel like wasting them over and over again. I think any leftover batteries should be converted into a certain amount of bubbles. Cause otherwise where would they go? They’d be wasted and just disappear. Not only that but our bubbles would be wasted on batteries we don’t use. It’s a big thing for people to buy bubble batteries for events every day. So if it’s valuable why don’t we get bubbles back if we have batteries left over? And since we buy 7 half for 300 bubbles for fashion they should sell for 300. And for collect/prank they would sell 500. Same with 15 full batteries. They should sell for 1,000 for whichever event since that’s what they sell for.
