Shelli's right about spending the extra to get the premium eyes- the ones with the U backing and not the o. Too often when you go to crimp the cheaper ones they break....so you saved money and lost money.....it isn't worth it. The premium ones barely need any crimping, just a wee bit at the very bottom.
I have yet to have one of the premium nes break on me. And I use sozes al they way down to 2 and 3 for the gollies....
But in bulk and it saves money that way
Also-for what its worth
I bought a spice wrack with empty bottles and thats where I keep my eyes, easy to get to, in their own little space, marked it works well
