Westcott ‎JR-12 Small Plastic T-Square for Drawing, DIY, Crafts, 12In/30cm

This is exactly what I was looking for! Finally a small,inexpensive t-square that is useable and convenient. I had one like this (different brand) that I used for years, but I broke it. When I tried to find another one, I learned that the brand no longer existed. I ordered several “lookalikes” on Amazon, but thy were not useable because the “lip” was so shallow, it would not stay aligned, also the “ruler tongue” was usually bent which made the t-square behave like a see-saw… can you imagine trying to draw lines with all that going on. But then this one arrived…perrrfect. I can hook the lip directly on the side of an envelope or heavy calligraphy paper and draw nice square parallel lines in a jiffy. I ordered 2 more as spares because I don’t want to do without this tool ever again. Get THIS one, not a cheaper variant that looks like this…I assure you, they are not the same. Westcott brand. Such a simple inexpensive tool, but it’s worth its weight in gold.

Works perfectly as I'm laying out light vertical pencil guide lines for reflections in water in my acrylic paintings

It's true that this item is flimsy, but for $5, I didn't expect better. I use it for paper-crafting. I am writing mostly to say that mine lasted 6 years, before snapping. For the price, that seems reasonable. I will order a new one.

It is a nice size and it is very easy to use and it helps me to measure my canvas it has very good Accuracy the stability is very flimsy it will break easily so be careful when you use. It is a very heavy plastic and very easy to read the numbers. Very good price for the money. It very stable won't move on the canvas. But like I said it break easily.

I'm replacing another one I bought that had the numbers fading. Not only were the numbers fading they were on the wrong side of the t-square. It was awkward to use. Numbers were upside down.

My main dislike of this is that the aligning edge is a little too thin to stay aligned/caught for applications beyond basic drawing. Wish everything was a bit thicker so it'd both flex less, and catch the edge more easily and with less risk of jumping. The space without an alignment edge under the "T" intersection, while traditional, is annoying because of the tendency for the plastic to rotate or flex when only the top or bottom edge is engaged.Honestly, it's probably great for applications where you don't want to clamp in place or have much pressure on any of the edges. (Like sketching/drawing.) But you want to use with clamps, wood, or metal it's just not sturdy and deep enough.

I lost a ruler like this and was so lost when it came to getting that perfect line for some projects. Now that I have it again I am very happy. The size makes it easy to store in my pencil cup and it doesn't make it tip over.

I like. It was perfect for making straight lines for my homemade Christmas cards.
