Features, Architecture & Package Contents

The fun should start when you run to get the mail and can't wait to open a Stirlingkit mystery gift pack, you don't know what will be inside. As mentioned before, we guarantee that our Stirlingkit boxes are cheaper than buying the items separately. When you buy an engine, buy a toy for your child. So this time we not only added engine models, but also some toys specifically for little kids.

The boxes we sell include different gifts. Your value will be better than buying them separately! Everything can be put into these mystery boxes for free. All boxes are sold as is and are not returnable. If you ask for a return, it is not a real mystery box!

All sets are pre-packed and can be shipped immediately after purchase. We grab them randomly from the stack and when they run out, we will pack some more.
