About Bert's Clay Creations

For more than 40 years, Roberta “Bert” Prostor has been sculpting joy out of polymer clay. A well‑known clay artist with a signature sense of humor, Bert built her reputation on handcrafted figurines that collectors adore. Today, she’s taken that same artistry and leveled it up into something fresh, functional, and irresistibly fun: badge reels, interchangeable toppers, lanyards, and buttons that spark conversations everywhere they go. From her studio in the beautiful Sonoran Desert of Paradise Valley, Arizona, Bert transforms everyday work accessories into tiny pieces of wearable art. Each design carries her unmistakable charm — a mix of clever humor, expressive detail, and handcrafted warmth.Read their story
