3. First Aid Supplies
Underrated and among things we usually forget to pack are first aid supplies, because as every seasoned traveler knows, accidents happen. First aid provisions such as band aids, bandages and disinfectant can also be some of the most difficult things to track down in a foreign country, especially if you’re looking for a particular product or brand. Making yourself a small portable first aid kit that fits into your carry-on bag is consequently a great way to be prepared for every situation that life may throw your way.
