Our take
The Ubuy indexed listing describes a JIKAI C30 7-gallon cube aquarium and reports UPC 768443142335, 30 × 30 × 30 cm dimensions, 5 mm low-iron glass, a rimless shape and a leveling mat. These are marketplace fields rather than specifications confirmed by a manufacturer; the page could not be opened directly during the saved check. The historical ASIN B09RMW5N4F is not mapped to a current exact Amazon offer. Treat C30 and the listed details as seller-reported comparison clues, then verify the exact item before relying on them.
A shopper comparing a marketplace-described compact glass cube who will verify model C30, its dimensions and the current package..
Not for a buyer who needs manufacturer-confirmed capacity, glass thickness, a known filter/light package, a verified current Amazon item, or an aquarium that meets a ten-gallon minimum.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The indexed listing gives model C30 and UPC 768443142335 as identity clues.
- It reports a compact 30 cm cube and a 7-gallon listing capacity for comparison.
- The seller describes rimless low-iron glass and a leveling mat.
What to weigh up
- No manufacturer source corroborates the model, size, material or included mat.
- The product page returned a cache miss, so only indexed fields were available for this check.
- The historical ASIN, filter, lighting, lid, stand and other package items are not established.

What the features mean for you
Treat C30 and JIKAI as marketplace identity fields
The indexed Ubuy title and detail fields name JIKAI, model or manufacturer part C30, and UPC 768443142335. That combination is useful when comparing a search result, but it is not a manufacturer cross-reference. The page was not directly accessible during the saved check, and no maker source confirms the code. Keep the seller-reported label visible in any comparison and do not connect the historical ASIN to another offer unless the current page independently matches the same item details.
A 7-gallon cube is a compact size claim
The seller listing reports seven gallons and 30 × 30 × 30 cm. The figure places the candidate below the finder’s ten-gallon minimum and in its compact size range. It is a marketplace capacity claim, not a measured water amount or verified usable volume. The listed cube dimensions also need confirmation on the actual item: external measurements affect space planning, while fill line and setup can affect operating water. Ask for a current specification or package label if exact capacity and footprint matter.
Keep the low-iron glass description qualified
Ubuy describes 5 mm low-iron glass. That claim is enough to compare the listing provisionally with glass candidates, but the maker has not verified the composition or panel thickness. The same indexed data calls the tank rimless; it does not describe edge polishing, seams or any warranty. Do not infer strength, clarity performance or safe support from the low-iron wording. Confirm construction and manufacturer identity with the current seller before selecting a lid, light, stand or other equipment around the C30 listing.
The leveling mat is the only named package accessory
The indexed details mention a leveling mat, but do not list a filter, pump, light, lid, stand or separate sump. Those items remain unknown rather than confirmed absent. This matters if you need a ready-to-run kit or documented filtration. In the finder, flexible filtration can retain the listing as a compact comparison; a hard sump requirement cannot be satisfied from the available evidence. Verify the exact current contents and installation directions, especially because the direct page did not load for this research record.
Compare it with a kit only on confirmed differences
PONDON PFT-005 is a different 5-gallon seller-listed glass aquarium kit whose regional reseller pages name a filter and LED. The C30 listing instead describes a 7-gallon cube, low-iron glass and leveling mat but does not itemize powered equipment. These source claims create a useful comparison in size, shape and listed package, not proof that either product is more complete or performs better. Keep their brands and model codes separate and verify each exact offer rather than copying package details across listings.
Use the tagged search as a lead, not an ASIN crosswalk
The Amazon destination searches for JIKAI C30 and the listed 7-gallon 30 cm cube, with buyershortlists-20 attached. It is not a direct link to historical ASIN B09RMW5N4F. Search pages may show other cube tanks, different sellers or a similar low-iron phrase. Check the maker or seller, C30 code, UPC, dimensions, material statement and included mat together. Current price, availability, condition, exact contents and support requirements are not established by the indexed listing.
What else to compare
For a nearby compact glass listing with a different cube-versus-kit tradeoff, compare PONDON PFT-005 at a seller-listed five gallons with a filter and LED described in the package. Its seller and variant limits also require checking.
Before you buy
What does the C30 listing say about size?
The Ubuy indexed fields report seven gallons and 30 × 30 × 30 cm. These are seller-reported details, not maker-confirmed specifications.
Is JIKAI confirmed as the manufacturer?
The marketplace listing names JIKAI and C30, but no manufacturer source corroborates those fields.
Does the seller list equipment?
The indexed details mention a leveling mat. They do not establish a filter, light, lid, stand or sump.
Is ASIN B09RMW5N4F a current match?
No. It remains a historical clue, so the affiliate link is a tagged C30 model search.
Can it meet a ten-gallon minimum?
No. The only saved capacity claim is seven gallons, which is below ten; verify the current listing if the size requirement is decisive.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.

The decision
JIKAI C30 is a marketplace-described 7-gallon cube with a reported 30 cm footprint, low-iron glass and leveling mat. Those facts are not manufacturer-confirmed, the indexed page was inaccessible directly, and the frozen ASIN is unresolved. Verify the model and contents before purchase.
