how long is that elastic going to stay tight?
love, someone who wears bras and knows about these types of things.
For a long time.
I've had 12 cards in mine for over a month (for testing purposes only). Today I took 11 out and tested it with 1 card, it still held securely. I grabbed the one card by the top and shook it...nothing came out. I held it upside down and gave it a shake...nothing while it was upside down.
I recommend 1-10 cards to keep the elastic tight and to extend the life of the wallet.
I went to Warped tour with this thing and went crazy when Chiodos/The Used played and everything was still there.
Hopefully my future video on the roller coaster can convince you that's it's secure
PS - Bra's go through washer machines. I recommend hand washing mine under cold water to keep it tight.
