The perfect pottery trimming spinning spinner for every ceramic artist. The Spin-a-pot pottery spinner uses a ceramic bearing for an ultra-smooth spin and see-through acrylic to easily find the center and see your clay beneath the spinner. The base is 2" in diameter (50 mm) and the spinner has a handy grip pattern on the side. The spinning trimmer will make your pottery trimming so much faster and more professional, and with the wider base, it helps prevent accidental bowing or breakthrough versus only using fingertips.
