What item from Dahl's brown paper bag was least likely to be used in daily grooming?

The item from Dahl's brown paper bag that was least likely to be used in daily grooming is indeed a pair of pyjamas. In the context of personal grooming, items like a toothbrush, shaving soap, and a razor are directly related to hygiene and grooming practices. They are used daily to maintain cleanliness and appearance. Pyjamas, on the other hand, are primarily clothing worn for sleeping and do not serve a function in grooming or hygiene. While they are an important part of daily life, they do not impact one's grooming routine. Thus, this choice stands out as the least relevant to daily grooming practices.
