I left mine in a pencil case and the contents shifting around was enough to remove the markings. This product shouldn't be on the market without a redesign: Markings should be etched into the surface to protect against abrasion. ### ⭐ Unusable *by S***Y on 1 November 2023* Had this scale rule under 6 months. It’s been in my design pencil case and has been used a few times before the MARKINGS DISAPPEARED!!!! It’s no longer usable. I imagine it’s because they aren’t laser etched, but only painted on. Real shame as others have been leaving great reviews. Disappointed and definitely not intended for pencil case storage for students!!! ## Frequently Bought Together - Rulex 150mm 15cm mini black metal triangular scale ruler with coloured stripes and Scales: side 1 – 1:1 & 1:5, side 2 – 1:20 & 1:10, side 3 – 1:50 & 1:100 - Rulex 15cm 6 inch Flat Oval Metric Black Finish Scale Ruler 1:1 1:100 1:5 1:50/1:20 1:200 1:1250 1:2500 - UK manufactured --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/130803926-150mm-15cm-mini-black-metal-triangular-scale-ruler-with-coloured](https://www.desertcart.co.za/products/130803926-150mm-15cm-mini-black-metal-triangular-scale-ruler-with-coloured) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-25*
