This set includes 7 types of LaQ blocks in 5 colors: red, blue, yellow, green, and black. There are definitely over 500 pieces (with a little extra). Each of the five colors (red, blue, yellow, green, and black) has 100 pieces (with a few extra to ensure accuracy). The types of pieces are included randomly. As a service, I will give you the instruction manual for one of the models from images 2 (numbered 1-5). Image 3 is an example of the Suzaku instruction manual. You cannot build all the models in the instruction manual with 500 pieces. These blocks are from various sources: hand-me-downs, gifts, and new purchases, and the purchase dates vary. The condition of the pieces also varies. There are differences in manufacturing batches, but they are all genuine LaQ products. I have inspected for dirt, cracks, and discoloration, but there may be some dirt that I couldn't remove, unnoticed scratches, or overlooked dust. Please understand this. I am selling these as used items that children have played with, so please consider this before purchasing. - Brand: LaQ - Colors: 5 colors (red, blue, green, black, yellow) - Number of pieces: 500 pieces - Features: Blocks of various shapes - Uses: Creative building play Thank you for viewing.
