Kids' U.S. DIVERS 4-Piece Snorkel Set, Foot Size 19.4-23 cm

The photos show everything. The contents are not mine, so I don't know the details well.
If you want to confirm anything further in the photos, please comment.
Only what is shown in the photos is included. If there are any unclear parts, please be sure to comment. The photos are everything.
The soles of the fins appear to have been used 4-5 times, and upon close inspection, there are many small scratches on the underside.
The mask also doesn't look very clean.
These are items I want to dispose of together as part of organizing my parents' home.
Everything included is shown in the photos, so if you have any questions, please be sure to ask.
