But that's so I can return my 24" large one to my sewing room. I thought about this one but most of my work with fabric and paper both require the L however both styles work great for construction and building and keeping things straight for cutting etc. These are fine. They are not the top of the line where the tool would cost over 50 each but they are perfect for my use and I tend to wear out super cheap styles all to quick. I do use the measurements but I am not as fussy as the other reviewer about which direction the ruler seems to go. That isn't always as important as does the ruler mark off correctly as is an inch a true inch. And therefore I'm happy with the L I choose for my book binding/paper craft room. My eyesight has a problem that can not be corrected by glasses that's gotten worse and one thing I do with the L is fold paper evenly edged which until a year or two ago I could eye perfectly now either of these tools is most helpful with that chore. I haven't had the paint rub off. And I have the 24" one for over 25 years so that's saying something and hubby now and again borrows it for his construction jobs. Those are rare times as he has his own tools mind you. The 25 year old one isn't this brand but they are similar in quality compared to my smaller 12" one from Mr Pen. **Q: how thick?** A: 1cm thick ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well made and useful *by A***R on January 8, 2026* Love the T Square. It is very useful for lining up my leather and getting the cut where I want it. Also, seems very well built. I will buy again from Mr. Pen. ### ⭐⭐⭐⭐⭐ Great product and seller! *by W***N on April 21, 2026* I rarely ever review anything on Amazon, but this is worthy of a review. Very nice product, would buy again. ### ⭐⭐⭐⭐⭐ Great for the Price *by J***E on March 28, 2019* Getting this T-Square is a solid deal for a cheap price. It does what it's supposed to do by providing 90 angle edges for drawing my architecture plans, sections, and elevations. I normally use a bigger, more expensive, T-Square; I got this T-Square because of it's smaller size that allows me to carry around when I am traveling and unable to go to the studio to work. This T-Square is made out of strong metal, which makes it quite durable, thus allowing it to sustain for a long time. Furthermore, it provides both inch and millimeter measurements, which I found convenient for my drawings. The only minor issue I have with this T-Square is it's thickness, as a thinner edge will make drawing square edges more efficient with better visibility for sophisticated linework. However, the thickness of the T-Square is understandable, as it is made out of sturdy steel, and the thickness doesn't undermine its function. If you are looking for a cheap, small, travel-friendly T-Square, this T-Square is a decent choice. ## Frequently Bought Together - Mr. Pen - T Square, T Ruler, 18 inch Metal Ruler, T Square Ruler, Drafting Tools, Architect Ruler, Set Square, Drafting Ruler, Tsquare, Truler, Architectural Triangle,Tee Ruler, L Square, Scale Ruler - Mr. Pen Geometry Set with 6 Inch Swing Arm Protractor, Divider, Set Squares, Ruler, Compasses and Protractor, 15 Piece Set - 6 Pcs Triangular Ruler Set 12 Inch Engineering Scale Aluminum Architect Drafting Ruler Metal Protractor Arquitectura Accessories for Students Draftsman Engineers Metric --- ## 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.es/products/88387683-t-square-t-ruler-45-cm-metal-t-square-ruler](https://www.desertcart.es/products/88387683-t-square-t-ruler-45-cm-metal-t-square-ruler) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-06-09*
