Hollow all the way through, so fish can use it.
It looks like bogwood and behaves like an aquarium ornament. No soaking for a fortnight, no waiting for it to sink, and no tea coloured water while the tannins leach out.

Why you'll love it
Genuine driftwood floats until it waterlogs, and leaches tannins that turn the water like weak tea for weeks. Resin gives the same look on day one with none of that.
Plenty of wood ornaments mould the holes shut for strength. These pass through, which is what makes it cover for plecos, loaches and anything else that likes a tunnel.
Bogwood softens water and drops the pH as it breaks down, which matters if you keep hard water species. Sealed resin is inert and leaves your parameters where you set them.
Good fit if
Look elsewhere if
Genuine aquarium wood leaches tannins for weeks, turning the water a light tea colour. Many soft water species prefer that and it is harmless, but it is not what everyone wants in a display tank. Real wood also floats until it is fully waterlogged, which can mean a fortnight in a bucket before it can be used.
Resin has neither behaviour. It sinks immediately and it is inert, so the water stays clear from the first day and nothing changes over the following month. What you give up is the mild acidifying effect real wood has, which matters if you were relying on it to soften your water.
Plenty of ornaments look like wood and are solid, which makes them scenery. Openings running right through the trunk turn this into shelter, and shelter is a functional requirement rather than decoration. Fish that cannot get out of sight stay stressed, and stressed fish colour down and pick up disease more readily.
It suits bottom dwellers particularly. Corydoras, loaches and small catfish spend the day under something, and a passage they can enter from either end is far more use than a cave with a single dead end opening. Check the openings are large enough for the widest fish that might try to use them.
At roughly seventeen centimetres it is a mid ground piece rather than a centrepiece in anything but a nano tank. Angling it rather than laying it flat looks considerably more natural, since wood in a river rarely lies parallel to the substrate, and it also creates a shaded space underneath.
Push the base into the substrate slightly so it sits rather than perches. Java moss and Anubias both attach to resin readily with thread or glue, and a piece with a little planting on it after a few months stops reading as an ornament and starts reading as part of the scape.

The details
Loved by real pet parents
I had real bogwood in a previous tank and spent six weeks with water the colour of weak tea while it leached out. This resin branch went in and the water stayed clear from the first hour. Same look with none of the soaking, weighting down or patience.
The openings really do pass through the trunk rather than stopping at a moulded dimple. My bristlenose found the tunnel on the first evening and now spends the daylight hours wedged in the middle of it. That alone made it worth putting in.
It does sink straight away as described, no soaking or weighting needed, which was the main reason I went for resin. At roughly 140 g it is light enough that a strong outflow shifted it in the first week, so I have buried one end in the gravel. Since then it has stayed exactly where I put it.
There are three branch shapes and I went for Style 2 because it has the flattest run along the bottom. The photos make the three fairly hard to tell apart, so I was half guessing when I ordered. In a 17 cm long footprint it gives a low horizontal line I could tuck plants behind, and it reads as real wood from a metre away.
I keep hard water species and real bogwood softening the water was exactly what I did not want. Six months with this in and my pH and hardness readings are where they have always been. That is the whole reason I chose sealed resin over the real thing.
The bark texture is convincing and holds up well to a brush during a water change. The green moss detailing is the weaker part, it sits a little too bright and flat against the brown and my eye goes to it. Loaches love the tunnel though, which is what I bought it for.
Out of the box it looked slightly too clean to pass as real wood. I wrapped Java moss around the thicker end with cotton thread and three months later you cannot see where the resin stops. The through holes stayed clear so the loaches still use them.
The listing does say about 17 by 7 by 8 cm and that is accurate, so this is my own fault for not measuring. In a 180 litre tank it reads as a twig rather than the centrepiece I wanted. Well made, the holes are genuinely open, it is just modest for a big tank.
I put this in a shrimp tank mostly for surface area and it has been ideal. They work along the textured bark constantly and sit inside the hollow when the light is on. No tannins meant I could keep the water clear, which matters when you are trying to count your shrimp.
Good questions
No. Rinse it under a warm tap to shift any dust and put it straight in. It sinks on its own.
No, and that is the main reason to choose resin. Sealed resin is inert, so it will not soften the water or drop the pH the way bogwood does as it breaks down.
They are the same size and finish, just different branch shapes. Buying two different styles reads as one piece of wood that has broken apart, which looks more natural than a matching pair.
No. It sinks immediately and releases nothing, so a rinse under warm running water is all it needs. Never use soap, since residue lodges in the texture.
No. Resin is inert, so it will not acidify or soften the water. If you were relying on wood for that, you need the real thing.
They are different branch shapes at a similar size. Two or three together look more natural than one alone, since real wood accumulates rather than appearing in isolation.
