This is definitely a plug and play kind of unit. I was surprised when I unpacked it as it was like cardboard. It’s very flimsy and cheap feeling ( I know it was not very expensive but the edges of the panels hadn’t even been smoothed down).
The door is like cardboard when you open and close it and it all slots together like a jigsaw. Literally parts stick out and slot in. 
It does the job as it only holds loo rolls, and I won’t be using it as a cabinet, but it feels like a college woodwork project to be honest (if it’s wood . ) It’s small enough to slot down the side of my toilet and looks neat. 
You can only tell it’s cheap and cardboard-like when you touch it and use it  wouldn’t buy again, and probably don’t recommend it. Cost me over £20 with postage. Not worth £10. Positive is it only takes 15 minutes to ‘pop’ it together.
