chips

Its a strange product, in the US they were ordered not to call them "chips", and call them "crisps" instead:

The product was originally known as Pringle's Newfangled Potato Chips, but other snack manufacturers objected, saying Pringles failed to meet the definition of a potato "chip" since they were made from a potato-based dough rather than being sliced from potatoes. The US Food and Drug Administration weighed in on the matter, and in 1975 they ruled Pringles could only use the word "chip" in their product name within the phrase: "potato chips made from dried potatoes". Faced with such a lengthy and unpalatable appellation, Pringles eventually renamed their product potato "crisps", instead of chips.

In the UK, they argued they were not "potato crisps" because they though their low potato content would get a lower tax rate.

In July 2008, in the London High Court, P&G lawyers successfully argued that Pringles were not crisps (the term by which potato chips are known in British English), even though labelled "Potato Crisps" on the container, as the potato content was only 42% and their shape, P&G stated, "is not found in nature". This ruling, against a United Kingdom value added tax (VAT) and Duties Tribunal decision to the contrary, exempted Pringles from the then 17.5% VAT for potato crisps and potato-derived snacks. In May 2009, the Court of Appeal reversed the earlier decision.
