I own 24 of these Japanese mesh zipper bags. A set of 8 (four 9" x 7" and four 8" x 5.5") cost just $9 on Amazon (with free Prime shipping). They are very well made and great for travel. I use one bag for tools, one for cables and batteries, one for medicine and first aid, one for small gadgets, one for eyeglasses, and one to store receipts. Then I just put them in my suitcase. I also use them at home to organize small parts. Amazon was sold out for a while but they are available once again.
