"Bouwjaar '63 felt cover + fashy hot water bottle" is a hot water bottle that is a collaboration between the Dutch "bouwjaar'63", which has wool felt items, and the prestigious German hot water bottle maker "fashy". It is light and easy to carry, and the hot water bottle itself is highly safe because it has been certified by a strict German inspection.


The cover is made of 100% wool felt, which does not easily absorb dust and moisture. It repels water and dirt well and has high heat retention. With a simple and sophisticated design that matches the "fashy" hot water bottle, bottles can be taken in and out smoothly.


Seven colors are available: dark gray, red, orange, dark pink, petrol, apple green, and moss green. The price is 8,000 yen (excluding consumption tax).
