Oh, most definitely! While we only use 100% authentic LEGO® pieces, we are not affiliated with or sponsored by the LEGO® Group.
We work with a company called Replay Bricks. They buy used LEGO® collections, then sort, wash, and sanitize the pieces which we then use to package our various challenge packs. The assortment and variety of LEGO® pieces in our packs is unlike what you can buy new in stores, since LEGO® has retired many pieces over the years.
