The Aura features a one-sided anti-splash texture made of spikes that are twice, as long as, those of the Sea Shell 3D Flat Urinal Screen, which help prevent splash back and cross contamination of urine to other areas outside the restroom. Manufactured using a specially engineered copolymer that is impregnated with organic deodorizing compounds that are 200% stronger than traditional vinyl urinal screens. Flexible to allow proper fit to any urinal contour. Translucent design allows total viewing of the drain to ensure it remains free flowing. Fragrance lasts 45 to 60 days. Packed 60 per master case.
