I bought this intending to give it as a gift, but that was not possible because it comes with no documentation regarding where it was manufactured or what material it is made of, and no care instructions. So odd, I have never bought anything before that had absolutely no documentation. A parent receiving this as a gift would want that information. I thought of printing out something from the manufacturer's webpage put I couldn't find anything helpful there. I could have printed out a screenshot of the product information from this website but that seems so tacky. So I bought something else to give as the gift. I later noticed that three years ago someone posted a review saying not to buy it as a gift for the same reasons, but I didn't see that until it was too late. And the manufacturer posted a reply to that review saying they would consider the feedback, but they haven't done anything.

Perfect for the child who likes to stack things or build. These foam blocks seem to be almost water resistant which I was hoping for. The large blue platform was what drew me in initially, the sides of our tub are rounded so our one and a half year old can't stack anything up on them although it doesn't keep her from trying. When the blocks are wet they somewhat stick together which I thought was great, easier for kids to stack and build. The storage hanging bag is a great quality bag it seems. We have toy hammock prior to purchasing this but I will be keeping the bag incase our current method of drying toys fails. The two ducks are not of high quality, just extra fun added to the set in my opinion.
So far no mold, will update this post after 6+ months of regular use and proper drying.

These bath blocks are awesome! My 4 year old son is fully entertained with them. I like them because they use suction to sort of stick together for stability in turbulent water. They are a sturdey foam material that dries very quickly in their mesh bag. I just hang it on the water spout and go back an hour later to put away. No disgusting moldy bath toys anymore! My son also just discovered that they stick to the wall of the shower. Very cool. We have had them for about a month and I would definitely buy again.

These work better than expected! They stack and stick together so well in the tub. My daughter plays with them each bath.

Update: still holding up well! They don't get grimey or moldy. They will also stick to the wall of the tub.

this is one of the best bath toys you can get a child we have had them for 2 years and they are still in great condition and they use them with every bath. they have so much fun with them.
