Can Lids

I designed these to fit USA standard cans so I could organize the large numbers of nails screws, nuts, bolts, etc. I have amassed over the years. The lids fit pretty snuggly on the can so they don't fly off if you drop them. I have a label maker so I do not need to try and read my cryptic scrawl.
There are two sizes. The cat food lid fits cat food/tuna cans and the dog food fits DOG FOOD CANS! Who knew?
As an aside, there are standard specs for the manufacture of these items that vary from country to country but I imagine one can scale them to your particular needs in your slicer.
