Inchy the Bookworm Vending Machine™ can hold up to 300 books total. However, this will vary depending on the tray layout you ordered with your machine.
Example :
Default chapter book trays have 5 book slots per tray, and each slot holds 12 books deep (front to back).... so a default tray will hold 60 books and there's a total of 5 trays per machine at max.
60 chapter books x 5 trays = 300 total book capacity
However, custom trays usually will have either 3-4 book slot per tray and those will hold anywhere from 12-16 books front to back. (these are the custom picture book trays).
The large books slots hold 16 books deep while medium size slots will be either 12 or 16 deep.
Custom trays will normally hold roughly 40-50 books per tray total.
So if you ordered your machine with some custom trays (which is common) then your machine would hold anywhere from 250-300 books total.
