Large Lexan Acrylic Terrarium Scienceware Bel-Art Products. Rare to find, I can’t find comparable items. Very large, 50 cm internal diameter. Designed for controlling atmospheric conditions for biological experiments. The top and bottom close precisely with a good seal. There is a single port for a hose attachment and vent on top. It has some scratches from morons using Scotchbrite to scrub it but with the right plastic restoration products you can get it like new. I used a little something I had to get it to the pretty nice appearance that you see. Maybe you’re not a scientist at all but it would make a heckuva table/aquarium/terrarium. Shipped well packaged by UPS
