Golden Ruler Designer Brass Wallet Fibonacci Sequence/Series Ratio Multi Tool Essential Metal Card 3.25"x2" (Black)

A REALLY UNIQUE, QUALITY TOOL AND FAIRLY PRICED. BEAUTIFUL AND WELL MADE. SMALL, YET EASY TO HANDLE AND KEEP WITH YOU OR ON YOUR DESK OR DRAWING BOARD. GREAT GIFT FOR ANYONE WHO HAS AN INTEREST IN CREATING, DRAWING, MODELING, SCULPTING IN AESTHETIC PROPORTIONS.

I love this for drawing, notes in class as well as just to have a rigid metal object for art projects. I personally have not used the measurements, but they are beautifully printed. I stress tested this by using it as a screw driver for a camera tripod plate and it worked well, obviously the metal bent because it was never intended for this, but it still works as intended to be a ruler. This is a fantastic gift idea, and it slightly smaller than a credit card making it slide into wallets extremely easily. TSA never flagged this, and they shouldn't either if that is a concern!

This card sized ruler fits into my wallet without making it bulky or uncomfortable. It is a beautiful and very meticulously designed little tool and I find it really useful when sketching out ideas. I’m really happy with the quality and it comes in a really nice sleeve. The attention to detail is a really nice touch. Definitely recommend it as a gift to someone who appreciates quality and is into design.

I would give this 4.5 stars, just needs the golden ratio numbers on the chart for the 5 star rating. I love how it's like a credit card, could easy fit in your wallet. The color is nice, its stable, the measurements are correct. It comes in a case that you could use for traveling as well. All in all, great product. Would definitely buy again.

Nice solid material has a good weight to it and good size to take on the go. Very helpful to check to see if thing are flowing nicely. As an artist inspiration can come at any time and it good to have this tool on hand to aid in getting thing just so.

The most elegant and beautifully designed little ruler that fits perfectly in any wallet! This would make an amazing stocking stuffer/gift for designers, makers, or anyone who appreciates a little aesthetic in their life.

I am a woodworker and this little card is awesome. I wish I thought of this. I keep the card in my wallet and you can't notice it. Adds almost zero bulk. The features are perfect for when you need a quick measurement or angle of something.

I gave this gift to a math teacher friend and he absolutely loved it! He keeps math-related gadgets on his desk at school since the students are always interested to hear about them. The product itself is very sleek and comes in great packaging that really helped to make the gift even more beautiful.
