Thought I was getting one size (width) staple in 3 different lengths - the description is very UNCLEAR and on the (illegible) picture of the packaging they seem to be the same width NOT THAT THREE different widths and lengths who has 3 different width tackers/hammers for all of them staples at the same time NUTS. ALSO some definite IQ "genius" designed the packaging. It's a clam shell that won't come together even if you can get all the clamps to work together (you won't). You need separate jars/jars to keep the unused ones. Worst packaging for staples. About what. Mine arrived broken and ALL strips of staples arrived broken up into tiny sections of 3-6 staples each. Oh what a treat to spend half an hour loading a hammer. NO. AVOID suicidal thoughts. run, don't walk
