【To those searching for a loved hat and about to undergo treatment】 I understand you may have anxieties. I know you are going through a difficult time. I sincerely hope that your treatment will be as easy and successful as possible. Please, don't overdo it. Take care of yourself. 【About the product】 Purchased from Ice Japan in March 2025 for 91,300 yen and used a total of 8 times from March to June. The hat and covers have been washed, and the cooler box and ice packs have been disinfected with alcohol. The covers were washed in a net after each use, so there is some wear and tear. There are no pets or smokers. Please understand that this is stored by a private individual. Please understand that this is a used item, and we cannot accept claims or returns. The cooler box was used for commuting to the hospital by car, from the parking lot to the hospital, and inside the hospital. Therefore, there are some scratches on the bottom, but there are no problems with its function. Other than that, there are no tears, and I think it is in very clean condition. 【Set Contents】 ① Hold Cap 1 (Black) ② Cooler Box 1 (Coleman) ③ Hard ice packs for cooler box 6 ④ Inner cap (light blue) ・Top of head ice packs 6 ・Top of head frozen ice packs 6 ・Side of head ice packs 12 ・Side of head frozen ice packs 12 ⑤ Instruction manual ＊↓ As a small token of appreciation, I will include the following as a bonus. ⑥ Disposable non-woven cap for use during hair loss purchased from Aquadoor (15 pieces in a pack, but only 12 are included.) ⑦ Hairband 【How to Use】 The cooling duration is 60 minutes per cap. Wear it 30 minutes before the start of chemotherapy and replace the set every 60 minutes. It was easier to replace the sets if you prepared them in advance. It is recommended to wear it for 90 minutes after the end of chemotherapy. It is said that it is better to wet your hair well each time you change the set. ← I purchased a spray bottle from a 100-yen shop. Although there is an instruction manual, please refer to Ice Japan's YouTube video for detailed usage instructions. It takes 2-3 days for the ice packs to freeze. We hope you will purchase with enough time in advance.
