This duster is made of thin, high-quality polyester threads that attract and remove dust effectively thanks to the static electricity generated by friction. It is designed specifically for use with the Max telescopic shaft, which has an adjustable length between 74-180 cm. The shaft and duster are purchased separately, so it is possible to replace the duster without having to buy a new shaft. To clean the duster, it can simply be shaken or rinsed with soap and water and air dried.
