These cans ARE NOT cut with a can opener. Beware of anybody online making these cans that will not show you a picture of the top of the can. The “teeth” on the can opener will leave small marks around the edges that are very obvious. If you have ever seen a homemade soda can safe made using a can opener, you know exactly what I am talking about! Check out these pics, you can see the can’s edge is 100% smooth and does not have any indentions what so ever.
