What can I say, they're plastic end caps. They are exactly as described and fit perfectly on cardboard tubes, they are not easy to take off to the tube(in my case). Which is perfect when you are using these in shipping, you do not want your products to fall out. Awesome end caps.

Great, cheap caps! For the price, you definitely can't complain. Sure, they're a bit more weak compared to most but they do what they're intended to do without a problem and they fit perfect in your average 3" diameter tubes - Not too snug, not too loose but I always secure my mailing tubes by a couple staples anyway.

Compared to the uline caps typically used, these are a slightly thinner plastic but it made it easier to staple through the cap and tube

Capping off each end of cardboard shipping tubing. Caps work really well...

These caps seem to be a little bit thin compared to others I have used before in the past from other suppliers, but these are priced well below the others which makes it a great buy!! If you need an end cap to fill the space for your tubes, then you will be happy with these.

So happy that these are now for sale here on Amazon. They work perfectly with any 3 inch mailing tube and stay put for mailing overseas. I run a small business and ship hundreds of posters across the world every year. Price is right, too.
