I was missing some V Pegs from my tent and I needed few extra pegs to secure my tent in sand on the beach. They worked pretty well for me.
Suitable for sand and/or muddy terrain.

Note: PLA is not suitable for hot summer temperatures (use something more resistant to temperature).
Note2: In my case the PLA pegs were one time use...they did the job very well but at the end when I took them out from the sand they were warped and bent(due to high temps), and in that shape were no longer usable.
