Let me explain why I recommend this in general. The main reason this is so useful in my opinion is the actual box itself. For me this was always the biggest annoyance, not getting a container that properly seals. The box also comes with a stack of papers and the sponge. I have found it works quite well. I have had paints last as long as a week when I remembered to top up the water.
So it is a wet palette and it fulfills the function of the wet palette perfectly fine. Though only reason I recommend buying this one is pure laziness. It gives you everything you need to get going. In the future you don't need to buy paper from PP so that will save you some money in the future. I got mine from Troll Trader. Honestly, I get a lot of my stuff from them because they are fast and reasonably priced. If you are happy making your own and happy with the results, don't waste your money. There are plenty of guides for making them, but as I said I was never satisfied with the end product. Were this one works perfectly fine for me.
