Did you know that along with your school’s recycling and composting program, using Flexi-Felt instead of buying tennis balls, you’re helping to reduce your environmental impact. The Flexi-Felt is made with a wool blend felt that is much more biodegradable than the synthetic tennis balls. It is also 4 times smaller and is guaranteed 5 years thus using 20 times less landfill space over 5 years! Since the Flexi-Felt also protects flooring very well, you also reduce the need for harsh cleaning and wax stripping chemicals while reducing the energy requirements with regards to cleaning and polishing equipment.
