Due to a flat-rate shipping campaign, the price is reduced from 1700 to 1500 until March 18th. I am selling this because I no longer use it. There is a brown stain on the corner of the medium-sized container, which does not come off even after washing and appears to be inside the glass. The lid has small scratches from use. I have washed and dried it in my home dishwasher. Individual sales are also available. Please comment. 4-sided lock for improved sealing!
