This is a set of keychains purchased at a ski resort souvenir shop in the late 1980s (the bubble era) when I was going skiing all the time. (From left to right) 1. KURUMAYAMA KOGEN SKI (Kurumayama Kogen) 2. I ❤️ SHIGAKOGEN (Shiga Kogen) with a heart 3. HAKUBA (Hakuba) 4. Winter Holidays TSUGAIKE KOGEN (Tsugaike Kogen) 5. SUN ALPINA Kashimayari, Aoki Lake, Sanosaka (with a small bell) The ring is about 2.5cm in size, so please use that as a reference. They have some scratches on the front and back, probably because they were stored in the same bag. SUN ALPINA in particular has a lot of scratches on both sides.
