This one easily punches staples straight through thicker stacks, then bends them correctly to secure the pages together.

Even with the Swingline 40 staples which are supposed to staple as many as 40 pages, the best we could do was 26 pages, and the points do not bend over to make a smooth underside

Often the back of the staple will come through the top page, sometimes all the way.

30 pages was a breeze.

Great deal, excellent product, valued Seller, highly recommended A++
