Sophisticated and chic, these Round Jumbo Printed Balloons will make an unforgettable statement. Each pack comes with one 36-inch (or 3 foot) balloon, that is 100% biodegradable. This means they are non-toxic and made of a special, high-quality rubber latex material. Crafted from rubber harvested on plantations that are Rainforest Alliance Certified™, these party balloons by Illume Partyware look good, sure, but they feel good too.
