I don't know if you all have seen these little leather or leatherette 7 day pill boxes around? Some of them are rather expensive but knock offs can be found at Walmart, Amazon and on Ebay. I found this one at Walmart and ended up going back and getting about 4 more. Why? Because when you take the pill box out and cut the elastic inside out they make the a perfect little 4 pack tote case for hauling most camera batteries. I particularly liked this one becuase it's shiny faux red croc, like one of my straps, and only $6. (They also had a zebra one and a black one.) Amazon sells a canvas version that might appeal more to guys and other some colors in a flat leather, non croc, but they're $10 and up. Note, you cannot buy the ones at Walmart online. They're a sold in stores only thing. Oh and there's a little wallet ID thing that matches if you need one of those too, but no regular sized wallet, alas. I saw a phone carrier for a big I phone too as I recall that was very similar. But it wasn't for me. My phone isn't that big, but both my K-30 batteries and my Oly batteries fit 4 to a case in one of these. It's very nice to have I think...
