If you are a camping fan and like to have a good rest with friends in the fresh air, then you have often come across how you observed a funny and sometimes tragic situation, when somebody stumbled over these tent pegs :)
Strangely enough, but it was the Chinese who were the first to launch and set up the production of plastic tent pegs with an integrated LED and operating on 4 LR41 batteries. The duration of the charge lasts about 5 hours. You can disable or enable them at any time by unscrewing / twisting the cap. Peg dimensions 21 x 9.6 x 8.5 centimeters, weight 22 grams.
