Hey there, your caps are great. Something that drives me nuts on the boat- I run a small crab boat here in AK- . . . The string on the caps I got from you is a simple thing that makes me happy every time I drop a cap. The old ones washed away almost every time.

I just need them to keep the cans securely closed here around the farm and like me, my farmer neighbors have lost most of their caps too so this is perfect for me. I will probably even come back to buy more so I have plenty on hand. These are the darndest things because you never know where they go no matter how hard you try not to lose them and you NEVER just find them here and there. Who knows where they go.
