35 mm 40mm 45mm 50mm ** CARE ** We recommend being gentle and taking good care of your clay cutters to ensure a long, happy clay-making life. Here are our tips for cutter care: Always clean your cutter with a damp cloth, baby wipe or soapy water after use Ensure that your cutter is completely dry before storing Do not expose your cutter to high heat (eg. do not leave in the hot sun for prolonged periods), as it will warp Do not use excessive strength or force on your cutter For smaller cutters, or cutters with higher detail, material build up is inevitable due to the small gaps. Use a small needle tool to remove the stuck clay before storing.
