Snorkel Set - Reef Tourer Adult, Anchor Child

I purchased this several years ago and used it twice, but I am listing it as I do not plan to use it in the future.
Please check the images for details, as I have uploaded many detailed photos.
We would appreciate it if you would consider this item as a used item that has been stored at home.
Although it is relatively in good condition due to infrequent use, I am not familiar with water sports as I only used it for light water play, so I cannot determine minor age-related deterioration compared to new items, including product details. Due to age-related deterioration, the rubber parts may feel a little sticky in some areas, so if you are concerned, please take care of them yourself.
Also, on the 8th photo, there may be some areas inside the transparent part that appear slightly whitish, but this is likely residue from washing with detergent (it has been thoroughly rinsed).
We would appreciate it if you would consider this item after acknowledging the above points.
