Assembly Time: 20 minutes

Estimated Delivery Time: 1-2 weeks depending on the country of the buyer

Material: Solid Spruce Wood 

Handcrafted: All parts of the product have been created by human hands in combination with machinery such as routers and sanders. Each item is hence unique in nature and no single item will be identical to another one. Manufacturing imperfections are part of the process too, so if you decide to buy one of these products you agree to receiving an item that is by no means perfect, but that has been created with a lot of love and care for the material and customer :)

Packaging: We want to protect our environment! That's why we from STEMerch EU decided to only use recyclable materials to ship out our products, such as paper tape and paper bags/filling.

Perfectly suited for STEM classes and exploration of tension and cancelling forces in physics and engineering!

*Only the DIY model is included in the final product.
