This auction is for a gently used Knex Storm Mountain roller coaster building toy.  It is model number 14148.  It has a motorized chain lift.  It has 646 pieces.  It is for ages 10 and up.  It is 4ft /1.3 m long and 3 ft/1M high.  I do not know if all the pieces are in the box or not.  I purchased it at a sale.  But the pieces are baged and taped inside.  The instructions are also included.  I cannot guarentee that all the pieces are there.  The cars also glow in the dark.  Here is a great summer project for your child. 

I will accept paypal or a money order.
