Pics are too small to see the details, but these are certainly Chinese in origin. Liuli technique (pate-de-cristal), popular from around the 90s onward, after Liuligongfang revived the technique in the late 80s in Taiwan, though mainland production seems to have peaked in the 2000s to 2010s. These were possibly made to celebrate the year of the Dog -- Chinese Zodiac animals are a popular motif in liu-li. If so, this would mean they were likely made for 2006 or 2018 Spring Festival. Are there any characters or other marks on them?
