This is a pocket mask made by Laerdal. I purchased it over 10 years ago and have been storing it at home. It has been opened, but has never been used. The accessories are all that are shown in the photos. [Condition] ・Unused ・Due to long-term home storage, there may be scratches on the case and the main body due to aging. ・There is a slight gap when the case lid is closed (please check the photos). ・The mask itself, the filter, etc. are unused. [Please Note] ・This product is a medical device, but it is being sold for display, educational, or collection purposes. ・Please understand and acknowledge that this is a long-term storage item and that there is a gap in the lid before purchasing. ・Please refrain from purchasing if you are concerned about minor details. I will carefully pack it with cushioning material and ship it.
