STAEDTLER Ultraflex Ruler 30cm – Shatterproof & Twistable (Box of 24)

Rulers snapping mid-lesson? Kids bending them into useless shapes by Friday? These 30cm Ultraflex rulers take the hit. Soft, flexible, and shatterproof — they twist into curves, hold their shape, and spring back straight when you need a proper line. Assorted colours (green, blue, violet, transparent) make them easy to spot in a shared drawer. One box of 24 covers a full class without the weekly replacement chase

• Shatterproof Ultraflex construction — no more broken fragments on the classroom floor
• 30cm length, soft enough to twist into curves, firm enough to hold a straight line
• Assorted colours: green, blue, violet, and transparent for easy identification in shared spaces
• Box of 24 — one box per class, no chasing individual replacements
