Definition
'Unvendible' describes items that are not suitable for sale through vending machines. This might be because of their size, shape, fragility, or inability to be dispensed properly. Think of large or irregularly shaped items that won't fit in the vending machine slots. It also applies to fragile items that could easily break during the dispensing process. Essentially, it means the item doesn't work well in an automated sales environment. It's the antonym of 'vendible'.
