Review on 🐠 Enhance Your Lifestyle with CORISRX B&G Aquarium Sponge Filter Foam - Water Media Pads: Sizing, Benefits, and More! by Nicole Jones

Folded in half and taped together. Then place it in a medium-sized FedX plastic mailer. It arrived in a Revain box big enough to put the foam in without having to fold it in half. Why? Basically, if you want a good piece of flat foam that measures what is advertised, don't buy it. The edges are taped over and the styrofoam has shrunk from lying folded in half more than obviously for who knows how long. It's not nearly worth the asking price. I half thought of sending it back because it's not as advertised. In the photos they show a perfectly flat piece of biofoam and that's not what you get.
