The Solas Utility wristlets are a cute little dynamo. They function like a wallet with the credit card organizer but the you can just slip on the wristlet strap and take them out for a perfect little purse. Like all Solas handbags these refreshing and sexy purses are cleverly trimmed with neon lighting that will finally put an end to fumbling in the dark for your keys or lip-gloss! (All bags run on double AA batteries)
