This is where Modern KNEX Coasters are made. I recomend Vertical Vegrance Track or newer except for the Son of Serpent, Thunderbolt Strike, and Scorcerer's Eclipse track parts except for the flexi rods (from supernova blast, double doom, and skysprinter, and blizzard blast types of flexi-rods. You know what I mean by that.) send me an email at firstname.lastname@example.org for a request. Send me your name, and your instruction you want on the collection on my email.
