Thank you for viewing! Unused item! Opened for photos. Material: 100% EVA Outer Material: Polyester Water Resistance Level: Non-waterproof Country of Origin: China [Important Notes] This material is sensitive to heat, so it is recommended to wear it indoors or in a place away from direct sunlight. Direct sunlight may cause deformation. If your big toe protrudes, you may find a snug fit uncomfortable. Please feel free to inquire before purchasing if you have any concerns about the fit or size. [Size Development for Japanese People] Developed after thorough research of the general size sense of Japanese people. [Material with Excellent Elasticity] The slippers are made of 100% EVA, a material with excellent elasticity also used in joint mats that absorb sound and impact. It is durable and won't easily flatten, allowing you to use it as your favorite room shoes for a long time. [Comfortable to Wear] The heel has a bulge that conforms to the shape of the arch, providing a good fit. The shape makes it easy to take the slippers on and off indoors. [Less Fatigue and Pain] The high-rebound material absorbs impact, reducing pain and fatigue. The sole is 3.5cm high at its highest point, making it convenient when cooking in the kitchen. The outer film has been removed for photos. It's 27cm, so I think it's a men's size. We aim to ship the same day. Thank you! ^_^ KS20
