This is an unused support tool that can be used for acoustic guitars, folk guitars, ukuleles, etc. ------------------- ⭐️ This is an innovative product that eliminates the hassle of attaching and detaching, and is a countermeasure for those with lower back pain. ⭐️ Compared to support tools from other brands, it is highly rated for its excellent fit and stability. ------------------- Size: 210*340mm ➡️ The type that clamps onto the guitar can damage the thin coating of the guitar, so suction cups are gentler on the guitar. ➡️ Because the area in contact with the body is small, the guitar resonates well. ➡️ The thick acrylic plate and large suction cups allow for stable playing and will not come off (limited to smooth surfaces). ➡️ The suction cups have tabs, so removing them is less stressful. ➡️ To attach, simply firmly adhere the suction cups. ➡️ It's the perfect size to fit in a guitar case pocket. ➡️ You can adjust it to your preferred angle, providing a high degree of freedom.
