### ⭐⭐⭐⭐⭐ Great to use.
*by F***N on 28 July 2024*

Last year my family purchased a helicopter chair for my birthday. When winter arrived I stored it away in our garden shed, unfortunately when I retrieved it earlier this summer I couldn't find the caps that covered the nuts that hold it together. Looked on Amazon and found these. Brilliant.
