This is a listing for STEM kit of 304 interlocking blocks to build a a tractor with pull back action. . It is recommended for children 6+ but I would say it depends on the child. Instructions are in the box and should be followed step by step.  My grandson and I pick the blocks for the next stage and then build, and we have had great success.

I combine shipping upon request.

Please contact me first if any issue arises, so I may seek a resolution before eBay is contacted.

I accept return within 30 days at the buyers expense.

 As with all small items please keep them away from children to avoid a choking hazard or other harm.

I share my smoke free home with a spoiled ShihTzu dog and a very Sassy cat.

I sell these items through various venues.
