【Inflates in Just 3 Seconds! Ultra-Lightweight Air Cushion】 Easy to store! A convenient item for comfortable seating even when you're out and about ✨ ✅ Compact & Lightweight Design Comes with a dedicated storage bag for easy carrying. When folded, it's **about 10cm x 8cm and weighs only about 80g**! You can easily slip it into your bag or backpack and take it anywhere. ✅ Complete in Just a Few Breaths! Set up is complete in just 2-3 seconds with a few breaths. No pump needed, so anyone can use it easily. ✅ Design Focused on Comfort The interior is divided into air chambers to distribute pressure across your entire bottom. It's comfortable to sit on for long periods of time, reducing fatigue. ✅ When Actually Used... If you use a pump, it inflates firmly, but when inflating by mouth, some air escapes when closing the valve. Even so, it still supports your bottom well, so you can rest assured. In fact, it's more comfortable when it's not overly inflated, as it sinks in slightly, making it easier to sit for long periods. ✅ Quick to Pack Away! Open the valve and the air will escape quickly, deflating in about 1 second. Storage is stress-free. ↓ Useful in Scenes Like This ・For outdoor activities like picnics and camping ・For leisure activities like fireworks displays and sports観戦 ・For long journeys on the Shinkansen (bullet train) or airplanes ・As a chair cushion for work or studying ・Recommended for disaster preparedness and emergency use ◎ 【Product Details】 ◉ Color: Black ◉ Weight: Approximately 80g ◉ Size: Please refer to the second image 【Please Note】 ・As this is an imported product, there may be some loose stitching or small scratches/stains. ・We have opened the product once for inspection. ・We will ship it in simple packaging (waterproofed). ・The images may differ slightly in color from the actual product due to light and environment. ・There may be slight variations in size. 【Returns and Exchanges】 ・In the unlikely event of a clear defect, please contact us before leaving a review.
