We love his attention to detail along with the simplicity and elegance in his handmade ceramics. \nThis year's design is an update to our previous collaboration: this mug features a slight a natural clear cracked glaze that will develop a beautiful patina over years of drinking coffee, making each cup uniquely custom to the owner. They feature a 'RUBY' stamp on one side and a neatly painted red glaze base. \nSee more of Phill's work at on his website.\nApproximately 10oz. Each mug is hand-crafted, so please allow for some natural variance from cup to cup and minor imperfections.","images":["https://cdn.shopify.com/s/files/1/0339/5565/files/2E3AE2A7-3B1A-49AF-A017-509EBABB3D2E_1_105_c.jpg?v=1780589330","https://cdn.shopify.com/s/files/1/0339/5565/files/F595C33A-3CC2-4FE4-8682-46F09C9FCC55_1_105_c.jpg?v=1780589347","https://cdn.shopify.com/s/files/1/0339/5565/files/4DCC1B80-1A87-4EDB-A614-8FCD98CBB909_1_105_c.jpg?v=1780589427"],"price":49,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:15.511Z"},"share_url":"https://firestarter.network/l/lst_ZijcHmQl","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
