Suits a crafting need
This is a great tool to use for card making. It's got a nice lip on it to stay aligned where you place it. For my needs it a good value for the money.

Very good for the price. You definitely get what you pay for.
It's a low-cost option. Works fine.

Perfect for my calligraphy
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.

Very easy to break
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.

Does what I want it to do!
This T-square is a little flimsy, not terribly so, but it's thin plastic. If you want something sturdy, find an acrylic one or maybe even wood. Having said that, my use for the t-square is to line up elements on cards and sentiment stamps. Both of which this will do without a problem. I'm not going to use it to cut straight lines in chipboard or anything like that so it doesn't need to be sturdy for me!

Arrived a little bent
The item arrived a little bent, maybe more like warped and I can’t seem to get it flat

Best basic staple in line drawing
This was the best investment for someone like me who can't draw a straight line. I definitely would recommend this as a basic staple.

Thin but very helpful tool
Works well. Plastic is thin so it needs a little extra care.

gute Qualität
Die beiden Teile sind wirklich genau rechtwinklig miteinander verbunden, somit ist es gut geeignet für präzise Arbeiten. Prima für Zeichner, Kontrukteure und Bastler, man kann das kleine Querstück prima an einer Kante anlegen und sofort eine Linie zeichnen die rechtwinklig zur Kante ist. Dabei kann nix verrutschen wie zB beim Geodreieck, das mus man ja dann genau anlegen und gut festhalten. Trotz niedrigem Preis sehr gute Qualität vom Material und auch von der Genauigkeit der Einteilung.

regla en T
El material es algo blando, pero cumple su función perfectamente. Encantada con ella. Centímetros y pulgadas cada una en un lateral pero con la misma orientación. Así, si estoy midiendo en cm y quiero saber cuántas pulgadas son, no tengo que darle la vuelta (como sucede con otras reglas).

So useful for calligraphy guidelines- HIGHLY recommend
I do calligraphy and this ruler is a LIFE SAVER; first of all, for calligraphy I need clean, straight lines which I'm guaranteed with this ruler. Secondly, the ruler is sturdy and clear so I can see the lines drawn previously. It's a simple tool, but I use it for basically every art piece and could not do without it. Also, when I first recieved it, it unfortunately arrived broken in two pieces. I emailed customer service and received a replacement quickly and without difficulty.
