Vintage Hazel Atlas glass jar (marked B 12F on base) filled with 26 pairs of new old stock Impressions brand earrings. UV reactive — glows blue-white along the bottom edges under black light, consistent with manganese dioxide content in vintage Hazel Atlas glass. A collectible vintage jar in its own right — square mason-style form with embossed maker's mark on base. No lid included. Filled with a mystery mix of gold tone and silver tone Impressions earrings, clip-on and pierced, various styles — all on original Impressions cards. Cards are thick plastic and may show slight bending from the jar but are not crushed. Part of the fun is discovering what's inside. Individual pairs from this brand typically sell $4–6 each. Note: As a found vintage item, there may be wear, dust, and other callouts I miss. As is, as seen, as found. No cancellations.
