Yes, your skin can bend a knife, but it can't stop a bullet.

Ok, it can sort of stop a bullet. It will still pierce your skin, but only marginally -- you'll still have to remove bullet fragments with a pliers when the threat is debilitated via flag-themed shield.

Thankfully, PROJECT: REBIRTH developed a flexible, impact-resistant super-suit to augment your limited invulnerability. 

And thankfully (again), they listened to your suggestions for an equally resilient wallet considering the last one -- holding a picture of your mother -- was lost in a very intense flamethrower exchange.

So, they granted you the Captain America Star Women's Loungefly Zip Around Wallet -- it reflects your padded, patriotic aesthetic in the following wonderful ways:

The exterior!

• Blue, black, leather-like exterior with carefully stitched appliques and red highlights -- this represents live-action seamwork and comic-accurate costume accents. 
  
  
• A zip-around zipper rendered in brushed metal.

The interior!

• Navy blue inner lining slathered with red, commanding CAPTAIN AMERICA logos.
  
  
• Black, leather-like slots for cards, IDs, etc.
  
  
• A center pouch with zip-up closure.
