Pop-Up: You can easily access your card by pushing up the front decker with one thumb. If your thumb is sweaty and slippery, please use both thumbs. The cardholder can contain 1-6 credit cards, debit cards, and other bank cards. Super Slim：With a size of L*W*H=3.9*2.5*0.7 inches, the minimalist wallet is ideal for every pocket of your clothing. You can also insert it into your handbag or wallet. RFID/NFC Blocking: All your cards will be hold well in the aluminum card case, which protect them from unauthorized RFID/NFC scanning. No cards dropping out. Money Clip: The clip at the back side is for your paper money or banknote. You can also clip the card holder on the belt. Men`s Gift Idea: All VULKIT wallets are included in the gift package, which is a good gift idea. Thanks to the VULKIT mechanism, all cards are pushed out in a step with a single push up, so you can immediately find the card you need. Easy thumb push, grooves on the front compartment increase friction, allowing quick access to the most frequently used card.
