Listed in GUC because there are some spots on the tank which are pictured in the last 2 photos. They’re not super apparent, they’re tiny spots, but they’re there. The tank is in EUC other than the spots which I tried to remove to no avail. I have no clue what they are but I think it’s a defect because it came to us like this. Size is 18-24 but I think it’s more 12-18.
