Brand new, unused! Instant purchase welcome! To keep the price down, I will remove it from the box and package it in a宅配袋 (delivery bag). It will be shipped via Yu-Packet Post. If you would like the box, it will be an additional 300 yen. 【Supports Tilted Necks!】 "We want to support the necks of people who are battling desk work with smartphones and PCs." Based on this desire, we thoroughly analyzed and solved the problems of conventional neck supports that tend to slip, and designed and developed the "Concentrated Fixed Neck Supporter." With this neck brace, people who feel pain from holding their necks in a forward-bent posture for long periods of time will naturally learn the correct posture of the neck while wearing it! 【Non-slip and Comfortable Fit】 The Monons neck brace uses a hard PP plate to firmly support the neck and prevent slippage. On the other hand, the inside of the main body uses elastic arc-shaped sponge, which perfectly fits the curves of the neck and chin, with almost no pressure on breathing. Furthermore, the main body uses 100% cotton fabric, which is gentle on the skin, has no irritating odor, and is safe to use on parts that come into direct contact with the face and skin. 【Ultra-lightweight & Portable & Easy to Use】 This neck support weighs about 60g, which is lighter than one egg, and does not put extra burden on the neck and shoulders even when worn. Also, it can be folded and put in a bag, and can be easily carried and used anywhere. In addition, the Velcro fastener is easy to put on and take off, and the length can be adjusted, so you can adjust it to the optimal range according to your neck size. You can also cut off the excess belt. 【Washable! Can be used cleanly!】 When wearing the neck brace, sweat may soak into the main body beyond the cover, but the Monons neck support allows you to wash the main body and PP plate, so you can wash away odors and dirt and use it cleanly. It dries quickly, so please feel free to wash it. ＜Note＞ Do not wash in a washing machine. 1200r7551
