I'm selling this because I ordered the wrong size. I only took it out for the photos. It's a new, unused item. The size is adjustable, extending to approximately 42cm at its maximum. The size may appear slightly different depending on where you measure, so please allow for minor discrepancies. Please refer to the photos with the measuring tape for confirmation. It will be packaged simply with bubble wrap and a paper bag. Shipping may take some time. Sometimes I can ship it out quickly. Thank you.
