Tropical Fish Keeping Set ?

【Limited Time Offer! Huge Price Drop】
￥19,800 ? ￥3,980
Don't miss this chance! (*^_^*)

This is a tropical fish tank setup kit ?
I bought it about a year ago because I wanted to keep tropical fish, but I ended up not getting any fish and kept the setup kit stored as new at home.
It originally cost around ￥30,000 in total.
This set should include everything you need except for the tank and the fish!

The food for guppies and tetras has expired, so it will be excluded from this set.

Included in the set:
? Magnetic cleaner for cleaning the fish tank
? Water conditioner (dechlorinator)
? Liquid to make tap water suitable for fish tanks
? Product that breaks down dirt just by adding it to the tank
? Product that creates bubbles and lights up with bubbles
? Water temperature regulator
? Thermometer
? Foldable black bucket
? Seaweed decoration
? Small item container
And more (everything shown in the photos)

I'm a beginner at keeping fish and not very knowledgeable, so I apologize, but this is a set I put together by studying online (*^_^*)
It's priced very low, so it's perfect for those who want to try it out casually. ??

Thank you for your consideration!
