This is a travel pouch for storing passports, etc. I purchased it but never used it, and it has been in storage. It has RFID blocking and anti-skimming functions, so it can safely protect cards and passports. The inside has two pockets, and there are three zippers on the front, as well as a small transparent window for tickets, etc. There is also a mesh pocket on the back. It seems to be well-made and very easy to use. The size is approximately 18 x 15 cm, and the length of the strap is also adjustable. This is a stored item, so it's for those who don't mind. Please refrain from purchasing if you are sensitive to such things. #Safety pouch Black Black
