House of Marbles Spiromania

【Create Repeating Spiral Patterns】 Place a gear inside the outer template, insert a suitable pen into one of the small holes and roll the cog smoothly around the teeth. Changing the gear or hole creates different geometric designs. 【Five Small Drawing Gears Included】 The compact set contains five plastic gears with several pen positions, plus the outer drawing template. Combining different cogs and holes provides a useful variety of patterns from a deliberately simple kit. 【Use A Long Fine-Tipped Pen】 A pen is not included, and many broad pencils or short-nib pens will not reach through the small gear holes. A slim ballpoint or fine-liner with a longer narrow tip is the most practical choice for smooth results. 【Use A Long Fine-Tipped Pen】 A pen is not included, and many broad pencils or short-nib pens will not reach through the small gear holes.

Add different colours to build more detailed artwork. 【Compact Retro Art Activity】 The set measures approximately 18.8 x 13.2 x 1cm and weighs around 30g, making it easy to store in a drawer or travel bag. Its seventies-inspired packaging adds nostalgic appeal for children and grown-ups. 【Pocket-Money Kit, Not A Precision Set】 Spiromania is a small, lightweight creative toy rather than a professional technical drawing instrument. Careful handling, the correct pen and a steady surface help produce the clearest patterns.
