The term 'A Fibre' is a type of natural fibre that is used in many industries. It can be found in two forms: ISTLE (5 letters) and COIR (4 letters). ISTLE is a type of fibre derived from the leaves of the Agave plant, while COIR is a type of fibre derived from the husks of coconuts. Both types of fibre are strong, durable, and resistant to water damage, making them ideal for use in a variety of applications.
