2Pcs Circle Template for Drawing Drafting Geometric Circle Ruler for Painting Circle Round Drawing Templates Plastic Transparent Circle Drawing Tool for School Office Supplies

Using for watercolor pencils, works well.

It's worth noting that this is semi-rigid template, not one of the flexible ones. I think they're made of a type of acrylic, so they do indeed flex a little bit, but not like the thin, super flexible ones. This is completely fine for me, but worth noting.I have a few circle templates, but they're all in inches, so it's really handy to have a metric set. I actually checked a couple of random circles with a caliper, and they are accurate to like 0.3mm or so - fully acceptable to me. You also get a really good size range which is great.Overall worth it. You get a good variety of sizes and they are in metric. I do kind of wish they did a metric/imperial version so you could see both, but it's understandable because they don't convert perfectly.

Small ruler came in properly with no damage. Now large ruler as soon as opened it had cracks to it.

A lot of circles

I like the large assortment of circles to choose from but the plastic is very brittle and one of mine arrived cracked on one edge. It was still usable so I kept it.

This is a pair of two circle stencils/templates.There is a good array of circle sizes over the two, from tiny to quite large. One also has degrees noted on the outer edge.Both also have a centimetre ruler along one edge, which is a handy addition.I got this for general arts and crafts purposes, to be able to make circles of varying sizes without having to use a compass and put tiny holes in the paper. It’s also easier than looking for jar lids of the right size to draw around, and infinitely easier to draw inside of something rather than sround the outer edge.They’re slightly bendy while still being relatively robust and since the whole thing is transparent (but green) you can easily see where on the paper you’re placing the circle. They’re a handy piece of kit for my crafting drawer.

These are quite thin plastic but do good service for marking curved corners on leather prior to cutting. They're metric too. £6 for the two gets you a wide range of holes sizes. I would have preferred something a bit thicker and more rigid but these do a perfectly adequate job.
