On those days when you really need only your phone, a credit card and an ID, use the convenient Keebos wallet.
Keebos' famous wallet is sealable and oriented sideways, so up to 6 cards are a 100% safe and secure.
On the Keebos cardholder, you will also find an elastic strap specifically crafted to help you easily grip your smartphone one hand. This is especially useful for bigger phones, which are tricky to hold in one hand when taking photos or typing.
