Favorite toy for my kiddos
[This review was collected as part of a promotion.] These are the best building toys! All three of my kids (4,8,9) love to play with them. There are so many things you can build with them. They play in the tub with them, bring them outside and play all around the house. The quality is top notch and they are extremely durable and easy to clean.

Disappointing!
My granddaughter receive three of these for her first birthday in January 2024. She stays with me three days a week so having multiples meant she could have some at both house. They were great to begin with. Unfortunately, now they are not so great. She can build with them but the blocks no longer stay together. She makes a stack of them and when she tries to move it, it simply falls apart. The same thing happens when my husband or I build with the bloks. It is as if the plastic has stretched so the holes are too loose. Each set she received as gifts has the same issue. I do NOT recommend these building blocks. (NB: You ask if this product was received for free - yes or no. Since it was a gift, I did not pay for it but a family member did.)

Just the right size for toddlers
[This review was collected as part of a promotion.] My granddaughter loves building blocks. She was so happy when I gave her these. They are the perfect size for her, especially since she is only 2. I did receive this for free in exchange for my honest review

Perfect bloks for tiny hands
[This review was collected as part of a promotion.] First Builders Big Building Bag is great for little hands. The bloks are easy to put together and take apart. The colors hold my childs interest and allows her to build anything she can imagine. I like the the blocks come in an easy storage bag. I can take the bag with me when I need to give her something to hold her interest other than at home while she is playing.

Awesome building materials!
[This review was collected as part of a promotion.] These blocks are some of my favorite for kids of all ages!! My 5 year old loves them, and some of his favorite things to build are garages for his cars, and huge towers! The color selection is amazing, and his favorite blocks are definitely the orange "flags" to put on top of his creations!

Always the best choice
[This review was collected as part of a promotion.] As always, mega blocks never fail. There are so many things you can build and always encourages creativity and imagination. I love that you can combine these with any other set and they all go together regardless of color. They always bring the fun for hours without fail.
