Perfect for a 1 year old!
Awesome for a 1 year old! I was a bit skeptical if my son would be able to play with the blocks, but after showing him how to take them apart and put them together slowly several times, he seems to be getting good at it, he can pull the pieces apart and place them on top of each other, getting there. Also the quality is great, and the pieces are big enough not to worry about choking hazards. There are a lot of pieces of varying designs so you can create fun structures and watch your little one take them apart.

Great Toy, Fun
My toddler has so much fun with this block set. It’s a good size and I’m not afraid of stepping on the floor and hurting my foot with these. I would say these are durable after I’ve seen what they go through. The age range is accurate. It feels safe enough since these are huge and I don’t have to worry about small pieces. These really bring out my kids creativity. They also enjoy the variety of colors and I like pointing and asking what color the blocks are so it’s also kind of a good learning tool at the same time. They are easy to assemble, but can be a little time consuming to put away since there are so many pieces and you have to find each one (well with my kids at least lol). I also appreciate that it came with a nice storage bag to keep everything in one place. I love toys that come with their own containers to help keep things organized and no missing pieces.

Very Good
These blocks are great for kids. They keep them entertained for ages, and the quality is excellent. Plus, there are plenty of them to build whatever you want with the little ones. My daughter plays with nothing but these blocks; she loves them.

Love them
My toddler absolutely loves these. They’re easy to pick up. They have their own case and they’re great for little hands and little creative minds. She will spend forever building these things and we used them to go over her colors and her counting. 10/10

Fun for the Little one
Daughter loves these things, but I do wish this set included larger 4 peg pieces. The majority of the pieces in this bag are the single peg ones so not great for constructing larger builds.

O produto veio em uma caixa de papelão bem embalada, achei o prazo de entrega rápido para o MT. A sacola das peças é super resistente bem feita, eu fiquei encantada com as peças, são como na descrição, tem de todos os formatos, o tamanho é excelente para bebê, fácil de montar. As cores são muito vivas brilhosas, eu amei e meu bebê também, ficou horas desmontando e brincando.
