Languo Mechanical Pencil Set with Case, 4PCS Drafting Pencils 0.3mm 0.5mm 0.7mm 0.9mm

All-in-One Drafting Kit
The MP-360 mechanical pencil set includes four professional drafting pencils (0.3mm, 0.5mm, 0.7mm, 0.9mm), four tubes of HB & 2B refills, three erasers, and a durable storage case. Multiple line-width options meet all needs for writing, sketching, exams, and technical drawing in one complete 11-piece kit.

Durable Metal Build & Balanced Weight
Each pencil features a sturdy metal pen tip and built-in weighted components, providing a low center of gravity for improved stability. The ergonomic TPR soft anti-slip sheath ensures a secure and comfortable grip, effectively relieving finger fatigue during long use.

Anti-Break Core Structure
A spring-buffered internal mechanism absorbs vertical impact, greatly reducing lead breakage. Retractable pen tips (0.5/0.7/0.9mm) protect the lead during carry and prevent accidental damage. The 0.3mm model uses a fixed non-retractable tip for maximum precision.

Precision Drafting Performance
The extended tapered pen tip expands your field of view, making it ideal for precise drawing and detailed work. Smooth HB & 2B leads provide consistent ink-like lines that resist breakage and glide effortlessly for writing, sketching, and technical drafting.

Practical Functional Details
Features a pen-clip window for quick line-width identification. Built-in spare eraser allows for emergency corrections anytime. The comfortable grip and smooth writing experience make it highly suitable for students, artists, architects, engineers, and designers.

Professional & Portable Storage Case
The compact, exquisite storage box keeps all pencils, refills, and erasers neatly organized. Easy to carry to school, the office, or the studio, and convenient for long-term protection and storage.

Instructions
Before installing new lead, make sure the old lead inside the pencil is fully used or removed. To refill, remove the push-button cap, take out the eraser, insert the lead, then reinstall the eraser and cap, pressing several times until the lead extends. Please use the correct lead size for each pencil model.

Precautions
Do not unscrew the pen tip during normal use to avoid lead breakage. Do not insert lead directly from the pen tip—always insert from the back after removing the cap and eraser. If the pen tip becomes clogged, unscrew it and clear the blockage with a fine needle before reinstalling.
