{"type":"firestarter.listing","listing":{"id":"lst_a0Lbk_3B","product_name":"BG Cocktail Glass","category":"B Grade","description":"Nearly all Mazama pieces are created using a skilled, hand-crafted process. The natural by-product of this unique approach is that some styles don’t meet our specifications. These styles are called “b-grades” and offer some charming qualities.\nWith glassware, these “imperfections” will include micro bubbles in the glass, rippled surfaces, uneven lips or misaligned maker’s mark stamps under the base. We’ve photographed a selection of these “blemishes” to help give you a good idea of what you can expect. That being said, some pieces may vary slightly from what you see here.","images":["https://cdn.shopify.com/s/files/1/0044/9802/products/MZ-B-Grade-Sale-Thumb-7.jpg?v=1620884717","https://cdn.shopify.com/s/files/1/0044/9802/products/MZ-B-Grade-Sale-Glass-Defects-5_083583a5-0f52-45ad-91d4-d7ceeef6f686.jpg?v=1620884717","https://cdn.shopify.com/s/files/1/0044/9802/products/MZ-B-Grade-Sale-Glass-Defects-3.jpg?v=1620884717"],"price":20,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:54.469Z"},"share_url":"https://firestarter.network/l/lst_a0Lbk_3B","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
