Both items are used. The liquid appears to be about 50% full when the lid is opened. The powder is about 80% full, please check the photos. Competitor's Clear has a fast curing time, so I think it's suitable for salon work. Since it was used for treatments, there is a possibility that fine dust and dirt may have gotten in, so please refrain from purchasing if you are concerned. The liquid was purchased in 2024, but the powder was purchased around 2023. Both are used items and have been stored at home, so please understand this before purchasing.
