Why do these arrive in plastic cases with a hole on 1 end that you cant hang them using? If you hang using the hole,the ruler falls out?

I don’t think the hole is for hanging. The plastic sleeve is to protect the ruler edges and printed marks from scuffs and scrapes, and the hole is to let a bit of air in so it’s easier to slide the ruler into and out of the sleeve.

Will these ruler stick to magnet? I am looking the stainless steel that can attract to magnet.

Yes these rulers are made of a magnetic stainless steel. They are excellent quality. I am very pleased with my set of four.

Are the marks etched on both side not just printed?

They are etched, and on both sides. These are a very nice set of Stainless steel rulers. I am completely satisfied with my 4 piece set from this seller.

price for a case of them how many in a case?

Since the option to purchase a case was not listed on the information page, that would be a question for the seller, Mr. Pen, not the community of users who typically purchased the advertised four pack and can typically only share their use experiences. There is a Mr. Pen link top right corner of the page below Buy Now where you can submit a question directly to Mr. Pen. They will probably be thrilled to get an order for a case!

Si se ven bien. El acabado de los bordes un poco filoso. No tanto como para cortarse los dedos (creo).
