Can I hold a bag with hands that have hand sanitizer on them?

The issue is what your hands touched right before touching the bag. In the guide for the Ranch Bag, YEOMIM lists alcohol, cosmetics, pain relief patches, and hand sanitizer side by side, noting that contact with these may cause damage or staining to the product^[1]. None of the four are special items; they are things used daily on hands and skin.

Therefore, what matters is not avoiding them, but the order. Right after applying sanitizer, your fingertips are still wet, so wait a few seconds until they dry before grabbing the handle, and the same applies on days you use hand cream or sunscreen. For pain relief patches, it is safer to wrap them separately so they do not come into direct contact with the lining. In general, because faux leather is made by applying a thin coating layer on the surface, alcohol or oils can easily soften that layer or leave stains. If it is a bag made of Faux Leather like the Medium Slash Hobo Bag, this is something to pay more attention to^[2].

The same applies to storage after use. For the Harness Waist Bag, it is recommended to leave the opening open in a cool place for good ventilation^[3]. If zipped up and stored deep in a drawer, the moisture accumulated inside during the day has no way to escape, so after returning home, it is better to widen the opening and set it on a shaded shelf.

However, these instructions do not accompany every product. Among the 173 products collected this time, 18 had laundry and care methods written on them^[4]. hmmm, therefore, rather than a special precaution unique to those bags, these two lines read as guidance that can serve as a reference when handling bags made of the same family of materials.
