3.6x300 Black Zip ties, 100 pack

Long ties mean that you can stock up on one size for many applications. EDIT 7/14/15 - I don't know why the below reviews are negative, other than competitors, because I have used over 900 ties and not a single one broke for any reason. These are 3.6mm ties (light duty).

Mala calidad. Unos vienen muy resecos y se rompen al apretarlos . . . . . . . . .

Really good price. Worked great for atttaching foam tube insulation to my PEX plumbing. Thanks for the help. Saved me a lot of time and were very secure and were so slender that they didn't interfere with any curve or placement.

These are terrible. I purchased 200 of them (I literally needed 6) and was accidentally given 600....Unfortunately they're extremely brittle and will not hold up at all. The ties fail in a few different ways. 1) bend it in half. If you just bend the zip tie in half, it will snap. 2) try to pull it apart. if you close the zip tie and then try to pull it apart, it will likely snap. 3) twist it. if you twist the zip tie near the locking mechanism, you'll likely break off the plastic tab that catches on the teeth of the zip tie, rendering it useless. This tab can also be broken by pulling on it while "locked." Overall, these are highly disappointing and I cannot trust them to secure anything of value. Now, you can probably get away with grouping together computer wires or in my case, securing cables to my bike. However, if you have anything important that HAS to remain intact or attached, I would seriously NOT recommend buying these.

These are every bit the quality zip tie you are looking for. Buy them without hesitation. The Zip Tie sellers that begin with the word "Cheap" are exactly that in both cost and quality. They break at the slightest provocation and urge you to spend a little more to get a useful product for the job intended.
