Ours for a Year: training tool

It has been almost 3 months since I posted a Tuesday Topic! Not that I haven't had questions. But Tuesdays would go by before I could get the question posted, and then I'd miss my opportunity for the week, since heaven forbid I ask a question on Wednesday or Saturday. Because then it wouldn't be a Tuesday Topic!
Once again combining my love for sewing and for dogs, here are some treat pouches or bait bags that I made. A couple years ago, my puppy group gave out Gentle Leader/Premier pouches, and I loved it. Eventually, the French hinge wore out and broke, but I loved the stay-open convenience of that hinge.

I knew the hinge feature was one I wanted to incorporate in my own design because it's so easy to pop open and slap closed. But I also wanted to try to improve on the overall design, including other features that I personally found useful.

My pouches have enough room to hold a ball, in case Cabana ever wants to play. (She likes to retrieve when no other dogs are around to play with, kind of like, "Sure, Mom, I'll play with you IF there's no one better.")

The zipped outer pocket holds a cell phone or other items that you want to keep secure.

And on the back, there's another zipped compartment for keys and ID, with an open pocket for easy access to a poop bag. The design of the back panel also helps keep the pouch from flopping around too much when you're walking or running.

The webbing strap is adjustable and has a loop to insert a carabiner. I like to clip Cabana's leash onto the carabiner and go hands-free. (Mandy made me the pictured leather leash, and I LOVE LOVE LOVE it--the color, the length, the texture. A number of volunteers at the shelter have commented on how nice it is.)

I am trying to decide whether to make and sell these treat pouches, before I invest in more supplies. But I need a little market research first, which is where this post and the GIVEAWAY comes in! I tried to incorporate features that I'd like in a treat pouch, but is there anything I've left out? Here are some questions I'd love to get feedback on.

• Which of the included features are most appealing to you?
• Are there other features that you think I should add?
• Is my color selection too boring? Should I be using bright colors and prints instead of solids? (I also have it in solid burgundy, but it's not pictured.)
• What would a reasonable price be for these pouches, remembering that they are a handmade item (no sweat shops or overseas production)?
• Are there already too many competing bait bags like this on the market?

I would appreciate constructive feedback with specific information (not just "those are nice" please). A random winner will be selected to receive a free treat pouch in the color of your choice. If possible, I will even try to incorporate your preferences into the design. I will announce a winner next Tuesday morning, May 10, 2011. Thank you in advance for your help, I really appreciate it!!
