These protective cases, crafted from tanned animal hide, are designed to encase and safeguard small notebooks used for recording numerical data or keeping score. Often featuring a simple, robust construction, they provide a durable and weather-resistant housing for the enclosed notebook. An example includes a craftsman making a durable holder for their field notebook used for recording inventory numbers.
The utilization of these items offers several advantages, including enhanced protection against wear and tear, improving the longevity of the notebook. Historically, they were favored by surveyors, field researchers, and individuals involved in manual labor, owing to their resilience and portability. This practice ensures that vital information remains accessible and legible, even in challenging environments.
