They work well
Some of these tools are better than others, but worth it for the good ones. Every time they play with the sand these come out. A couple of the building forms are a bit big, you would need the bigger size bag of sand to fill them up, but the smaller ones work great. The slicer, bricks, and block and post pushers are the best.

Highly recomend - pieces for older and younger kids!
Great set! I almost needed to buy two because my kids play with the building molds inside the house with their trains and cars and they didn't want me to take them outside. Fortunately I eventually convinced them that these would be fun in the sand box too. The molds were a little smaller than I expected, but turns out that just means they are kid sized and not adult sized. The set includes more sophisticated tools for older kids, and fill and dump molds for the younger kids. I highly recommend this set!

Pieces are small
I was excited to purchase this to play with my grandkids. When it arrived I was surprised at how small the pieces were. This will make a tiny sand castle. Just beware of this. For the price, I thought it would have bigger pieces. On the other hand there is a large array of molds and fun little sculpting tools and gadgets. Some of these I may have to work with to figure them out!

Sand molds and tools
I bought these with the thought it would help my very artistic grandson create something amazing.. While he did create really awesome stuff, this set is super cheap and thin. They aren't gonna last long. But they'll work this season. I just hate plastic in the landfills. So I should have looked for something stainless maybe?

Small size, perfect for sandbox!
I ordered this set for the indoor sandbox I made my kindergartner during the current shelter in place order. I was thrilled that the molds are on the small side(mostly fitting in my hand), and quite sturdy. These are perfect for an at-home sandbox, and compact enough to easily take to the beach when we can do that again. Great product, perfect for little hands!

Nice set of castle molds
Nice unique pieces that should make a nice sand castle. Smaller than I expected but that's my own fault for not noticing the pic with dimensions listed. Set comes in a basic plastic bag so make sure you have a bag to carry them in if going to the beach.

A lot of fun, even for an adult
I had a chance to go to the beach with my husband and decided that I might like building a sand castle so I bought this set just for me. Some friends joined us with a 14-month old. I watched her carefully with the white sculpting tools, and she enjoyed playing with them with me. I made lots of little castles and then made a larger jack o lantern just before we left. I had a lot of fun and would recommend this set.

Great purchase!
I spent about 2 weeks choosing molds before I decided to go with this pack and I’m so glad I did! They are perfect for kinetic sand! We had 3 bags of sand here and there were more than enough molds to play with. They’re the perfect size for children and adult hands. They’re durable and when the mold comes out I was surprised at how much detail they had. This product exceeded my expectations. The kids love it and as you can see by the photo I attached I used them for my castle too!!
