Lightweight and sturdy
Picked a package of these up in order to set up the rainfly for my hammock a bit easier if there didn't happen to be accommodating trees where needed. They seem to hold well in both loamy soil and more sandy rocky stuff. Used them for a week in the Virgin Islands when camping and they held great for the whole time. Bright blue color is nice as they pop out if you drop one. They seem well constructed but are light enough weight that I don't mind carrying them even though I might not always need them.
