She is three. Her brother (five) immediately wanted to play with them and they have had many hours of great imaginative play. They are much larger than you think they are looking at the picture and came in a very large box. They are very well made and worth the price. However I bought them during the big Prime day for $65 less than they usually cost! I was so pleased! Highly recommended for children. I think they will still be using them several years from now to make roads, buildings, and anything else their imagination comes up with. The first thing my granddaughter did was make a house and deposited herself and her bears inside the house being very pleased with herself...please buy these for your children if you can afford them or ask family members to go in together to buy them as a Christmas or birthday present. They will last for years and be passed on to their children. Update: My grandchildren are much older now and still play with these blocks regularly. Est purchase I ever made for grandkids. They are heavy. ### ⭐⭐⭐⭐⭐ Heavy duty and nontoxic *by on Reviewed in the United States June 21, 2026* Fantastic quality!! I am so impressed. It's heavy duty! It's nontoxic and has no odor. Absolutely love this!! ### ⭐⭐⭐⭐⭐ Stellar block set! *by on Reviewed in the United States September 5, 2017* Silly expensive, however, these are one of the best toys you can get your kids if you can afford the splurge. My girls (1 & 3) have used these at least once, usually several times, a day since we have purchased them. So far, they prefer to use these for games where they arrange the blocks in various configurations on the floor and walk on them. Blocks are sturdy and holding up great to lots of rough play. I'm confident they will last a super long time and make a great hand me down gift for a friend once our girls have outgrown them. And such open ended play options! Love these blocks and the creativity they are inspiring! ## Frequently Bought Together - ECR4Kids Hollow Block Set, Wooden Toys, Natural, 18-Piece - PicassoTiles 50 Piece Race Car Track Building Block Educational Toy Set Magnetic Tiles Magnet DIY Playset 2 Light Up STEM Learning Construction Kit Hand-Eye Coordination Fine Motor Skill Training --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/3676689-ecr4kids-hollow-wooden-building-block-set-18-piece-natural](https://www.desertcart.jp/products/3676689-ecr4kids-hollow-wooden-building-block-set-18-piece-natural) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-27*
