Brand New Metropolitan Systems Complete T&G Flooring Glue

I have 18 bottles of Metropolitan Systems Complete T&G flooring glue available. These are brand new, completely unopened, and have been stored safely indoors at room temperature (never frozen, so the emulsion is perfect). This is a professional, commercial-grade adhesive that you usually can't buy at regular retail stores. It is made specifically for tongue and groove joints on floating engineered wood or laminate floors. Selling for $18 per bottle. If you want to grab the entire lot of 18 bottles at once, I will let them all go for $324 total. OBO
