Ravensburger GraviTrax Flextube Expansion Set

Your marble run system gains creative variety and fluid mobility with the Ravensburger GraviTrax Flextube Expansion building kit. These twistable tunnels, which are compatible with the original GraviTrax or GraviTrax PRO starting kits, enable marbles to move up or down at nearly any angle. The cutting-edge Flextubes bend in the middle, providing builders with more control and countless options for track construction. This STEM-focused add-on is ideal for kids ages 8 and older since it promotes experimentation, creativity, and practical learning of motion and gravity. The Flextube set is an excellent method to add to and improve your GraviTrax creations, and it is made from premium materials for long-lasting sturdiness. 

Delivery Costs, Ireland and Northern Ireland

• Free delivery on orders over €70. Under that, delivery is €7.
• Large items — go-karts, swing sets, playhouses and the like — are delivered free of charge, anywhere in Ireland and Northern Ireland.
• International delivery is calculated at checkout.

Delivery times

Order before 1pm, Monday to Friday, and your order is usually on its way the same day. Most orders arrive the next working day, and nearly all within two. Very occasionally — during busy periods like Christmas, or if our courier runs into a delay — it can take a little longer, so please allow up to 5 working days.

Bulky items

We deliver large items ourselves rather than hand them to a courier, so they arrive properly and in one piece. That takes a little longer: please allow 1-2 weeks. We'll give you a call to arrange a day that suits you.
