Strong Tubes come in Big 9/16" diameter and Regular 1/2″ diameter widths. The Big Strong Tube is ChuBuddy's strongest product. You should start with the Regular or Big sizes if you have an aggressive chewer. All Strong Tubes are hard and smooth. They are rated ChewFactor 3, which means they are among our most durable chews.
Strong Tubes are hollow and are available on a clip-on or neck lanyard. They are made in the USA.
Children should not run with a Strong Tube in their mouth. Wash tubes with warm, soapy water or place in the dishwasher on the top rack.
