This is a twist-and-decompress crystal egg. Its surface features a geometric crystal-cut texture that creates a crystal-like refractive effect under light, giving it a more three-dimensional and refined appearance. By gently pulling upward and lightly rotating, the egg unfolds layer by layer along its internal spiral structure, forming an elegant, fluid twisting motion that delivers a smooth and engaging decompression experience. When released, the structure naturally springs back to its original shape, restoring the egg to its complete crystalline form.
