Question about collectible placements

[Ariel.]

Hi, so, I really want to rearrange my collectibles on here, but I don't know how?
So, does anyone know how to do this?
Thank you!

You can't re-arrange collectibles. They are in order based on when you (or someone) bought them.

You can always ask people if they want to trade for other dates though, or sell them and buy a new batch with other dates.
