165 PARTS - The K'NEX K-FORCE K-20X Building Set includes 165 K'NEX pieces that kids can combine to build four different target and blaster models. This set contains K'NEX rods and connectors, plus special parts to create different exciting dart weapons: one blaster chamber, two skull dart holders, one quick-fit grip, one preload ring, and five foam darts.
BUILD, CUSTOMIZE, BLAST - The K-FORCE K-20X Building Set lets kids design and create the blaster of their dreams. Unleash kids' artistic side by letting them create their own dart blasters. They'll broaden their imaginations as they transform the main K-20X model into three alternate modes. This K-FORCE Build and Blast set lets them shoot five foam darts up to 75 feet!
DOWNLOADABLE INSTRUCTIONS - K'NEX K-FORCE K-20X has easy-to-follow step-by-step building instructions for the three alternate blasters and target figures that can be made from the same set. With the array of models kids can build, this toy is designed to give kids a more exciting and mentally stimulating playtime. Youngsters will soon be assembling complex structures by themselves!
MULTIPURPOSE - The K-20X Building Set is compatible with the entire K-FORCE Build and BlastTM line. Use the K-20X Building Set in combination with other K'NEX sets to build even bigger blasters and targets! K-FORCE dart blasters were designed for durability - special rod-locks included in the set help the parts stay together during the heat of battle!
STEAMaginationTM - This is the connection of STEAM (science, technology, engineering, arts & math) with a child's natural curiosity and creativity, and it powers the fun of each and every K'NEX building set. Building with K'NEX puts children on a path to a fundamental understanding of STEAM / STEM subjects.
CUSTOMIZABLE BLASTERS - K-FORCE Build and Blast is the only line of dart blasters that you design, build and fully customize! Specialized parts like quick fit grips and dart launching mechanisms combine with the K'NEX building system to create any blaster that you can imagine. Packaging may vary.
COMMITMENT TO QUALITY - K'NEX rods and connectors are responsibly made in America at a landfill-free, zero-waste green manufacturing facility in Hatfield, Pennsylvania. We test to the strictest quality and safety standards, ensuring that your child has a successful, trouble-free building experience.
PARTS GUARANTEE - Broken part? Missing part? If you need a replacement for any reason, just give us a call! We'll get you what you need so that your child can get back to building as soon as possible.
