Thank you for viewing! This is a Kairo (body warmer) cover made with fluffy and warm microfiber towel fabric. Perfect for Hakukin Kairo and disposable Kairo (mini size). The plain,落ち着いた色合い colors make it easy to use in the office, during commutes, or at school. By putting the Kairo in the cover, it softens the excessive heat and keeps a comfortable warmth. It doesn't take up much space in your pocket or bag, making it convenient for cold weather対策 in winter. Size: Approximately 9 x 12 cm (Due to the thickness of the fabric, the actual inner dimensions are about 8.5 x 11.5 cm. Please check the size of your Kairo.) Colors: Bluish gray and light gray with a calm color scheme. Material: Microfiber (fluffy, soft, and heat-retaining material) Care Instructions: Hand washing is recommended. Use a net if using a washing machine.
