Mushroom anchor, anchor set

I had this in stock but am listing it as I don't have the opportunity to use it.
Would this be suitable for those who own rental boats or aluminum boats?
The orange mushroom anchor is new and costs around 3,000 yen, a medium-sized anchor (5-7 kg) costs around 6,000 yen, and a large anchor (10-15 kg) costs around 10,000 yen, totaling approximately 20,000 yen. I am offering it at a low price.
Also, as this is a large item, direct pickup is possible in the Yasu City, Shiga Prefecture area, so please leave a comment. Thank you.
