I purchased this on Amazon on July 11, 2023, intending to use it for my commute. However, I discovered that a colleague has the same one, making it awkward to use. I've only used it twice and have kept it stored away since, so I'm putting it up for sale. The cooling performance is excellent, but I was personally bothered by the noise level. Functionality has been confirmed. ☆ The Type-C charging cable and instruction manual have been discarded, so only the product itself will be sold. However, it can be charged without issue using any other Type-C cable. Purchase price: ¥10,500 - Brand: DesertWest - Type: Neck Cooler - Design: Curved shape - Function: Cooling function
