The soft rubber is very gentle and soft on handsBicycle inner tubes are made from a super durable butyl rubber, which is non-toxic and super strong. Great for collars and leashes, not great for landfills. PUP-A-TIRE partners with local bike shops and clubs to gather tubes that would otherwise be tossed into the landfill.
