My 3 year old son played with these at our chiropractor's office and fell in love with them, so I got him his own set for home. We already had regular wooden blocks which he and his 5 year old sister play with on almost a daily basis, but tree blocks are way cooler. This would make a great and unique gift item. I would definitely buy these again and we plan on getting another set to add on to our block menagerie.
