【Wave Stretch Ring】 This is a wave-shaped stretching device that can be used for stretching the neck, shoulders, and back. This is not a product of Maki Sports. Although it is an overseas product with the same shape and size, you can definitely feel the stretching effect. (I also use it every day) Highly recommended for those who find it difficult to afford the regular price from the start, and for those who want to start exercising affordably! With its wavy curved shape, it fits: ・Around the neck ・Shoulders ・Back and allows you to easily stretch just by lying down. It is lightweight and doesn't take up much space, making it ideal for relaxation time at home or post-workout care. Product Name: Wave Stretch Ring External Dimensions: Length 24cm / Width (center) 10cm / Width (sides) 13cm / Height 8cm 【Color】Pink There may be minor scratches due to it being an overseas product. This does not affect the stretching effect, but please reconsider your purchase if you are looking for a perfect product. Thank you.
