Two rooster-shaped bottle openers, decorated with beautiful colored enamel on a copper alloy material. I believe they are both male, not a male and female pair. One is finished with enamel on both sides, while the other has enamel on one side only, with "BRONZE" (青銅 - bronze) and the material name on the bottom. Nowadays, with pull-tab cans and plastic bottles being the norm, it's rare (or rather, almost unheard of) to use this type of bottle opener in daily life, giving them a retro feel. These bottle openers were found while organizing. There are some minor stains and scratches (as indicated by the arrows in photo 4), but there are no deformations, and the colored enamel is also in good condition with almost no deterioration. It's uncertain whether they are Japanese or Western, but I believe they were acquired during the Showa era when bottle openers were commonly seen in kitchens. Note that the English word "enamel" in Japanese can mean "shippo" (七宝 - cloisonné), but it is unknown whether they were made using the cloisonné technique. Approximate size (mm) and weight are as follows: [Double-sided Finish] Length: 114, Width: 69, Thickness: 3 / Weight: 77g / [Single-sided Finish] Length: 107, Width: 66, Thickness: 2 / Weight: 52g / These are retro bottle openers decorated with beautiful colored enamel. They can be used perfectly well as bottle openers, but I think they can also be used as small interior decorations or even paperweights.
