Yes, my 3rd ever 5 star review on Amazon is for staples...,
This review is from: Tacwise Heavy Duty 53 Series Staples 8mm (2000) (Office Product)
Customer review from the Amazon Vine Programme (What's this?)
Tacwise staple guns are superb quality, but as staples go these are excellent. I was doing a project in the garden involving lining and the cheap no-name ones from the usually very good local DIY shop kept jamming. Poor. But these were excellent and I also went on to do some upholstery work on a boat. Not an ocean going superliner you understand, just a narrowboat. I'm not made of money!
These didn't jam once and the superb Z3-53 stapler takes these or nails, which is superb. I wish I'd had it to hand when I was doing other things on the boat like fixing trim, I can tell you.
Despite the fact that very few staple sizes are covered by any actual standards (US do specify some, and there is a German DIN standard for ONE size only!) these staples will happily fit other manufacturers machines.
