Our leather bags are sturdy and meant for arduous everyday wear. To keep the leather clean and soft, we recommend first cleaning your bag with a moist cloth then using a natural leather cleaner such as this beeswax cleaner.The wool used on our bags is felted by hand and is not synthetic. It can become fuzzy or pilled over time. To remove pill or lint, carefully "shear" with scissors, a lint roller, or a shaver, such as this defuzzer. Felt is water-resistant, but we do not recommend immersing your bag in water. Rather, spot clean it with soap and water.
