They work well, no jambs or breaks.Like the product and timing - just so hard to navigate to find an odd item - if a company (not this one) sales a stapler they should also sale the staples. It made this time difficult to locate.Work in my swingline tacker but are a little small for the holder.I needed staples for my stapler. I ordered these staples. They fit my stapler. Now I staple stuff. Done.I bought rapid stapler and this together.I had to customise rapid stapler because staples it get stucks and you have to keep taking out.. Not recommendedI got no time to write customer service about the problem.My fault, ordered wrong size. Didn’t return as item was heavy and thought it would cost more than the item!Super fast despatch and deliveryPerfect fit genuine part!! Will order again!I'd already had some of these and found them to be great staples to fit the stapler, bought in a variety of sizes to be used according to the thickness of what's to be stapled. The 6mm size being for backing paper and borders on a display board.
