Dear Sir/Madam, This is RobSchultz from US. I'm looking for products with the following specifications:We are interested in your 12 Liter bucket, We would like to have the beads rolled at the 1 and 2 gallon marks? is this possible? I am sending a drawing for reference, but you bucket geometry may be sufficient as manufactured. We are main concern is the bead rolls to indicate the 1 and 2 gallon marks. Units do not have to be powder coated you can price with or without. Show More
