For those seeking darker lines, consider a softer lead grade if available. ## How to use 1. Unscrew the top of your compatible mechanical pencil. Insert one or two rOtring 0.35mm HB leads into the pencil's lead reservoir. Ensure they feed smoothly into the mechanism. — Load the Lead 2. Click the pencil's mechanism (usually the top button) to advance the lead to the desired writing length. Avoid advancing too much to prevent breakage. — Advance the Lead 3. Use the pencil for writing, drawing, or drafting. The HB hardness provides a good balance of darkness and erasability. Use a quality eraser for clean corrections. — Write and Erase ## Product details | Field | Value | |---|---| | Base Ink | Water | | Special Feature | Extra strong composition, easy to erase | | California Proposition 65 | Contains Lead | | Recommended Use | Drafting, Daily Writing, Note-taking | | Serving Size | 12 leads per pack | | Cost per use | 12 leads at {{ccc_offer_price}} — {{ccc_price_per_unit:12:lead}} | | Shelf life after opening | N/A (consumable leads) | | Reapplication math | N/A (writing instrument consumable) | | Contraindications | May be too light for artists seeking very dark graphite shading. | | Allergens / common irritants | Contains Lead (as per California Proposition 65) | | Brand | Rotring | | Model Number | S0312410 | | Item Name | rOtring Replacement Leads for Tikky Mechanical Pencils, 0.35 mm, Hard Black (HB) (S0312410) | | Line Size | 0.35mm | | Hardness | HB | | Color | Black | | Material | Lead | | Grip Type | Smooth | | Package Quantity | 12 Count | | Item Weight | 0.013 pounds (0.01 kg) | | Item Dimensions | 0.276 inches width x 0.787 inches height x 3.15 inches length (0.7 cm x 2.0 cm x 8.0 cm) | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### How is this rOtring Mechanical Pencil Leads item authentic vs the version sold in Indian stores? These rOtring 0.35mm HB Black Fine Mechanical Pencil Leads are sourced directly from authorized US retailers, factory-sealed, and imported per-order. They are the same SKU and formulation that US buyers receive. All customs duties and GST are included in the displayed price, and delivery arrives in {{ccc_delivery_eta}} via ExpressBox tracked shipping. ### Will the leads I receive match what is shown on the US retailer's page? Yes, orders are placed against the listed US retailer page at the time of purchase. Batch codes, packaging, and labels match what the US retailer dispatches. Photographs of every order are taken before international handover to ensure accuracy. ### What is the best use for 0.35mm HB mechanical pencil leads? 0.35mm HB leads are ideal for precise writing, detailed note-taking, exam preparation, and technical drawing. Their fine point allows for clean lines and neat handwriting, making them suitable for students and professionals who require accuracy in their work. ### How long does a pack of 12 mechanical pencil leads last? A pack of 12 leads typically lasts a student or professional for several months of regular daily use, depending on writing intensity and frequency. The exact duration varies, but the {{ccc_price_per_unit:12:lead}} makes it an economical choice for consistent supply. ### Are these rOtring leads suitable for drafting and technical drawing? Yes, the 0.35mm fine point and HB hardness of these rOtring leads are well-suited for drafting and technical drawing, allowing for precise lines and detailed work. Their smooth writing quality ensures consistent output for technical illustrations. ### Can I use these leads for art or shading? While these HB leads are excellent for writing and drawing, they may be too light for artists seeking very dark graphite shading. For extensive artistic shading, a softer lead grade (like 2B or softer) might be preferred. These are best for precise lines rather than broad strokes. ### Are there any side effects of using these mechanical pencil leads? The primary consideration is that these leads contain lead, as noted under California Proposition 65. While safe for intended use as writing instrument refills, avoid ingestion. For standard writing and drawing, there are no adverse side effects. ## Compliance No product-specific compliance warnings identified.
