Triangular scale
Well the one that is pictured is not the one that was sent .we ordered 4 all together and they all were the wrong one. So we kept them hoping that they can be put to use somehow.

Exchange
The cashier was so helpful and a gentleman named Joe was as well. I had bought an engineering scale by mistake in a staples in Jenison Michigan exchanged it without a receipt even at the store in Holland Michigan. These two folks were very helpful and I got the scale I needed.

Wrong measurements!
I thought this was an Architect's scale... but it has different increments. I'd return it but I already tossed the packaging.

Triangle ruler
I purchased this thinking it was Imperial but it's metric. I was unable to use it but did swap it out. If you're looking for a metric ruler this is the one.
