Classic toys like LEGO building blocks never go out of style. A quick Google search even proves that there’s a whole web of online stores devoted to selling and buying rare, collectible pieces. There’s one standard 2×4 LEGO brick on the market, entirely made from gold, with a firm asking price of just under $15,000 – to each their own. Then, there’s Mokulock, an alternative type of building block. Carved entirely from sustainably sourced timber and not compatible with plastic building blocks, Mokulock works in the same way as LEGO bricks but is a couple of steps ahead on the road towards sustainable toy production. Coming from a love for trees and the natural world, the designer behind Mokulock recognized the waste that manifests with forest thinning and decided to make use of the smaller trees that are too thin for architectural purposes or furniture-making. Prioritizing simplicity and organic structure over shiny paint jobs, the Mokulock building blocks maintain their original tree’s finish, without additional finishing oil, chemical paint, or glue. While the different timber species used to create the building blocks of Mokulock vary, a sanded finish that promises a soft feel and splinter-free play is guaranteed. Currently, Mokulock uses timber from Japanese Cherry, Japanese Zelkova, Japanese Bigleaf Magnolia, Birch, Hornbeam, and Maple trees to produce their building blocks, which provide different textures and shades of wood for either smooth gradient or color block building projects. Mokulock was initially created as a means for preservation and sustainability, but the timber used in producing these building blocks offers some mental benefits for the user as well. In addition to supporting an endeavor that provides a sustainable alternative to a worldwide beloved toy, Mokulock utilizes the soft feel of wood to help enhance creativity, stabilize the autonomic nerves by lowering the blood pressure, regulate an otherwise abnormal pulse, and generally calm the nerves. Then again, we don’t need research to remind us of the comfort that comes when we immerse ourselves in nature and notice the solidity of its surrounding trees, the soothing scent of freshly cut timber, and the warm feel of tree bark. Due to the tree’s natural coloring, Mokulock offers a wide array of shades for its building blocks. A natural camouflage color scheme is achieved through the varying natural gradient of Mokulock’s building blocks. Just like LEGO building blocks, Mokulock bricks can be used to create large-scale 3D scenes or smaller designs like automobiles or miniature pyramids. Mokulock stays away from using any finishing oil, chemical paint, or glue in the making of their building blocks to maintain an organic finish. Some of Mokulock’s building blocks come engraved with quirky scenes and characters for children to integrate into their buildings.
