The Proverbial Wallets are a set of three wallets designed to help keep you within your budget. The Proverbial Wallets communicate via Bluetooth with your cell phone to track your finances digitally.
The Bumblebee buzzes whenever a withdrawal or deposit is made into your account. The Mother Bear features a clasp that makes it harder to open the wallet as you approach your monthly budget. The Peacock grows larger when you have money and shrinks smaller when you don't. Check out the video to see the Proverbial Wallets demoed. I personally think the Mother Bear would make a great gift.
