Query: The longest lasting gift you'll ever buy!

I bought these blocks off another website where they sell two 50pc sets together along with a little wooden bookshelf to store them in. I bought them about 2 years ago for my 4 and 6 year old girls. They have played with these blocks more than ANY other toy we've given them. They make Barbie houses out of them, roads for match box cars, etc. I am planning on keeping them a LONG time. They are also great for when company comes over. I would buy these again in an instant!
