YIYATOO 30 Inch (75cm) Flexible Curve Ruler Flex Design Rule, Ideal for use: Engineering Drawing, Design Graphics, Garment Design, All Kinds of Painting

I gave it a low rating for stretchability That is good, (it should not stretch), but I wish it had been a little larger (in size, not length).

If you need to measure odd shaped things, this flexible tape measure works great. It's fairly stiff, so it stays in place while measuring.

I liked how this is a 30" flexible ruler - there are not many available in this size range and it was reasonable in price. I will use it to capture the curve of the body for sewing pants. It will be fine for my use but I noticed it can be confusing to read. Overall, it is 33" long but the first 1.5" and last 1.5" are not marked (see photo). One side is in inches and the other side is metric. The measurements in inches aligns with other measuring devices I have so it is accurate but the numbering of the measurements can be confusing to read. The photo provided of this product is not the same as what I received, very 10 inches is marked 10, 20, 30, but between those markers the inches are indicated in single inch increments (the metric side is marked the same way). For example, if you were to measure 12 inches you won't see "12" on the ruler but instead a 2" mark past 10" (see photo, the flexible ruler is white, due to it's flexibility it is challenging to capture the alignment against other rulers in a photograph but it is accurate). Additionally, the imperial system is not based on 10 but rather 12 and there are no special marks to indicate 12" increments.

Used this to get the profile on a concave, convex aircraft cowl. Then was able to make foam patterns for a mold. OUTSTANDING product!

I thought this would be easy to use to draw a curve for a buildout inside a van to camper conversion I was doing but it’s not stiff enough so you can approximate the curve of a wall but not duplicate it exactly without some trail and error. It’s not a one shot solution but it gets you close. I do not think I am using it for the purpose intended.

It was exactly what was advertised. Delivery was very prompt. I rented a Post Office Box to be able receive items that won't fit into my mailbox because my apartment is in a secured building. This works so much better

I needed a flexible curve ruler for pattern drafting and sewing. This works perfectly.

This did not help me at all could not get it to measure correctly. Wish I had found more info on this before I brought it.
