$16 for 80 staples? 4 per box? Anyone who buys these is an idiot

This looks like it's targeted at small manufacturers for distinct, high-quality but recycling friendly packaging. I see this as just a premiumish product packaging design choice.

It's about $0.20 per staple. The design of the boxes they're demonstrating use 2 - 8 staples per box depending on size and folding design. That's $0.40 - $1.60 which figures into cost of packaging. It's not unheard of for things like bespoke soaps to have extravagant packaging, jewelry, I can think of a few more, I bet you can too. Spending $5 on packaging for a ~$80 product wouldn't be out of line. I'm thinking in that number a box fully glued, stapled, or otherwise, internal packing material, any paper inserts, etc. So on avg. $0.80-per-box, meh sure why not.

I was picturing this being used for the boxes for much larger things, like office furniture.

Why not just glue flaps like a conventional box? The article makes the claim that this makes it harder to recycle, but I just have a hard time believing it. I’ve never once heard that glued box flaps were an issue.

Thanks. The article provided the numbers I quoted, which made no sense economically.

The core77 site basically shuts down my browser after the page starts loading (Firefox on android), has anyone experience similar? I'm curious what's going on, I basically have to force quit the app for it to go back to normal. It loads fine using chrome on android.

It crashed the browser tab for me - Firefox desktop on macOS.

Tried in both regular and private mode on Android and no crashes here.

All meaningful page content there is viewable without JavaScript for me, and is perfectly functional with insignificant CPU load on an 11-year-old desktop.

Also on Firefox. But I have NoScript.

I could have been convinced that the invention of overlapping box folds was meant to supplant this stapler. I’d take a bit of glue and extra box over having these little metal hazards everywhere when I go to flatten my boxes.

They claim it allows you to make boxes without material overlap, but I don't buy that. If you're using a material that's flexible enough to fold and there's no overlap at corners, won't the material wiggle/warp during transit leading to gaps?

Is it possible this didn’t exist already? Remarkable.

Seems like it'd be a much better product if it could just bend any standard heavy-duty staples. Having to use a specific brand of proprietary staples is a continuity risk (leaving aside that the staples are also wildly overpriced).

> The company that makes it, also called Cornervery, says it's a more economical way to make packaging; paperboard can be die-cut to minimize waste, there are no overlapping flaps required, and tape and glue are not needed.

But apply little bit of pressure at the top, and the vertical edges of your box open up and potentially spill the contents.

My daughter is an art major in college, I think she could find interesting uses for this tool. She's very much interested in how products are packaged.

If you squeeze the corner it turns into a gaping hole into the box.
