I've used this about twice, but I'm selling it because another product suits me better. It's the 2024 version, and it makes a high-pitched "keen" sound due to the tuning fork mechanism inside. Please note that the sound will not be produced if you cover the middle layer of the slider. The slider has a firm feel, like a "snap-snap" or "click-click" sensation. The contents include the ghost body, spare parts, and a plastic case. Fidget toy Fidget Ghost ghost Tuning fork Fidget slider Slider EDC Gender...Unisex Toy genre...Other
