Ya, i have the 20 Count Frankford one it is nice and slim.
I have seen the MTM one but the price is awesome $2-$3, but the shipping is what kills me. They charge $9-$15 for one item. Some sites i have to order $30+ to get free shipping.
As long as the rattling in the frankford cases dont harm the ammo then ill stick with that.
