I accidentally bought two of these, so I'm selling one. The item is unopened. This is a passport case with a dedicated AirTag pocket. The following text is quoted from Amazon: 【AirTag Dedicated Pocket】Equipped with a dedicated pocket that perfectly fits an AirTag, making it easy to find in your bag and helping to prevent passport loss. *AirTag itself is not included. 【Smart Storage Design】Features four card pockets, two SIM card slots (with SIM pin holder), one passport pocket, and one pen holder, allowing you to compactly store all your travel essentials. 【Secure Lock Structure】The built-in plastic lock structure on the back securely closes the passport case while still allowing you to quickly access cards and your passport when needed. 【High-Quality Material & Secure Construction】Made with high-quality vegan leather "Velo PU" material, with a stylish triangle pattern on the surface. The interior features RFID skimming protection, allowing you to use it with peace of mind while traveling or on business trips. 【Multi-purpose & Travel Specifications】With a D-ring, it can be easily attached to keychains, etc., for comfortable carrying.
