Hermitshell Hard EVA Travel Case for HP Sprocket Portable Photo Printer - Durable Protective Cover with Secure Fit, Compact & Lightweight Design (Blue) - Perfect for Travel, Home Storage & On-the-Go Printing

I actually bought this for some camera accessories because it was a compact carrying case that I could stick inside the main compartment of my camera bag and organize/contain whatever I held inside so that it wasn't floating around my bag. This makes it so I don't have to fish out any of these accessories while I'm on the fly. For reference, here's my bag: Waterproof Canvas Leather Trim DSLR SLR Shockproof Camera Shoulder Messenger Bag­ (Grey). This case fits long ways front to back on its side, alongside two filter wallets. It's the perfect size! The case itself holds my power accessories, so I know where all these things are when I need them. A power supply, USB cable, charging module, and 3 batteries.
