Comments about Staples® General-Purpose Poly Strapping Kit, 3,000':
The strapping is plenty strong and there is lots of it. The tensioner only gives a handle to pull on for one strap. The other strap must be held by hand. Buckles are bent wire and stick up. Shippers dislike them because they catch on things. The USPS will not accept metal buckles. They do have sets with plastic buckles.

I expected some plastic buckles but all of them are wire buckles. They are bulky and have sharp edges which is dangerous to other packages and workers in USPS, UPS, Fedex, etc. A tension cutter which comes with a box is useless. Staple should remove an image with plastic buckles from the product photo.
