【Product Details】
This is an unused product.

A rare 300x300x400 cube-sized high-type acrylic triple pipe overflow set with black silicone + custom cabinet?
Despite its small size, this popular 300 cube high-type set allows for serious breeding and aquascaping.

The flange processing prevents salt creep, which should also reduce water spillage from shaking due to earthquakes, etc.
(The custom flange part is clear specification only)

Unlike commercially available assembly-type cabinets, this is a sturdy, custom-made, finished product crafted by a woodworker.

Note: The cabinet will be shipped assembled. Although unused, please understand that there may be minor scratches from the assembly process.

Although it is a small set, it can be used as a main tank rather than just a secondary tank.

This is a custom-made set, so only one is available.

【Request】We do not answer questions regarding setup or fish keeping. Please only purchase if you have knowledge and understanding.

【Shipping Information】
*An additional ¥3,000 will be charged for shipping to Okinawa and remote islands.

*As this is a large item, shipping may take 7 to 10 days or more. If you are in a hurry, please inquire before purchasing.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
