Helix USA Circle Ruler, 12-Inch, Color May Vary, Assorted Colors (36001)

I will start by saying I agree with other reviews that this is thin plastic and feels easy to break, probably not a great choice for children or those who will be rough on it but it worked perfectly for my purposes. The rotating center piece has a small hole for a tack or finishing nail to hold the ruler in place while you rotate it to make circles. I found that a mechanical pencil fit well inside the holes, but anything with a thicker point than that may be too large. The rotating center piece popped out of mine on the first use, it is held in with small little clips and I was able to 'snap' it back into place with some force, none of the clips broke and it works just as well as it did before that piece popped out. I am laying out a Mandala on an organically shaped table surface and needed to make large perfect circles to map out the pattern - this was the perfect solution. Obviously functions as a regular ruler / straight edge as well, so it has value beyond circle making. 100% worth it for the $ compared to other similar options!

Absolutely perfect for circles. Best tool I ever found for circles.

I went looking for a simple tool to make circles and found this lovely item. It has made drawing circle guidelines a snap. It is a time saver. Easy to figure out how to use it. And the price was very reasonable. Five Stars If you are looking to make Mandala circles and need an inexpensive tool, this will work great for you.

A little hard to make a full circle without it sliding, but otherwise really good. Interesting, and useful

Works well, I would buy another one

This is a great ruler. I use it constantly for drawing circles, arches, and guidelines for calligraphy. I read some negative comments regarding it being fragile. This has not been my experience. I would highly recommend it.

I love this ruler. I broke my old one and had to purchase another one. I started using this ruler when it was recommended by a calligrapher. It's accurate as well.

not for kids. very flimsy. broke in half first day. great idea but need a better design.

I was a bit disappointed that the plastic is so thin but it does the job ok.

LOVE this gadget. So easy to use for designing circles for calligraphy.

Coming from a graphic designer, this is one of the best circle makers available. It features a simple, straightforward design. Compasses are great, but sometimes you need something quicker. Also, a compass can’t create the small circles that the stencil on this ruler can. I’ve tried many so called “top of the line” circle makers out there — but they all prove gimmicky (at best). Maped brand is the way to go. The only thing I would improve on is the flimsiness. This baby could snap right in half if you’re not careful. Wish they made one in stainless steel. Overall, great purchase.

Ordered this based on reviews by artists whom I respect. Being purely objective, it does what it is intended to do and does that well. However and as the pictures will show, it arrived with a distinct curvature in the middle. That is because it is plastic and very light and the curve is a result of the Centre placement of the pivot. That said, it does work very well and repeat circles seem to be accurate. It’s easy to use and I’m sure I will use it extensively. My only complaint is that I think it’s overpriced!

ce produit est exactement comme représenté dans l'article. Plastique très mince donc sûrement facile à briser. Facile d'utilisation. Reçu dans les délais et de couleur bleue.
