Does anyone know what the Maximum amount of Item box storage is?

[Pastakirby7]

I found out what the 4th use of gems is (1 being slot, 2 being fully refill original energy and 3 being fully refill ship energy)
and that is increasing the item box space by 5. Does anyone know what the maximum amount of item space you can have is? (Mine is at 90).

what’s the point of keeping inferior items?

Sell the gears with no added function except you want to keep the island-related ship gear (they’re poor though).

Where can I find island-related ship gear?

I always sell an item immediately when it pops up if I know it’s a lower level than what I already have. I was also wondering why you would spend gems to increase the size of your item box.
