I don't remember the exact number, but there were plenty of each color in our set. There were definitely enough to do all the designs suggested, with some left over. My son got this when he was 3 1/2 and loved it and played with it for a couple of years. It held up very well and we were pleased with our purchase!
I don't remember the exact number, but we received many of each color. We were able to make all of the design cards without running out, and there were enough to come up with your own designs. My son go this for xmas when he was 3 1/2 and loved it, and played with it for a couple of years. It held up very well and was good quality.
There are a 100 holes in the drill and desing set. There are enough to fill all the holes and then some. Awesome toy! We've had 3 years of playing with it and my son still loves it. It is fun to watch how they go from basic drilling the screws in and out to building the desings. It was a great purchase!
Every hole in the design board can be filled with what's included. I bought both sets and (travelling one and this peg board) and I have sooooo many bolts so if you ever need extra I'd be happy to send them your way!
