Strong stability and durability: Made of high-quality aluminum alloy + stainless steel, not easily deformed, corrosion-resistant, sturdy and durable, which can prevent outdoor shelters from cracking. Non-slip and adjustable: Equipped with spring buckles, which help to better secure the tent stakes and prevent the ground nails from falling off or rotating when the tent falls. Each one has double holes, making it very easy to lock the rope in place, adjust the length of the rope and secure the tent securely. Easy to install and disassemble: When installing the tent on a wooden board with gaps in the camping area, just insert it into the gap and rotate it to fix it. The board will not be damaged during installation. It is more effective when combined with a carabiner. For decks and planks: When camping outdoors, it can be used to install and secure tents and canopies on decks or planks. Portable and packing list: Small and lightweight, suitable for outdoor activities. Contains 5 fishbone tent stakes with spring buckles.
