5 Excellent Product
James on Sep 2nd 2025
<p>This product is perfect addition to my graphic arts 1 room studio. I am a minimalist calligrapher and use layout tools on a daily basis. I prefer the Alvin brand over any other because of the round center hole versus other standard triangles. They are just more comfortable to work with and I had lost my small triangle and needed a replacement that would be fluorescent thereby easy to find.</p>

5 There is nothing like an ALVIN triangle!
W. End 2 Design on Sep 14th 2024
The best triangles ever made. The color helps me find it. Anybody that still draws and drafts by hand would know how terrific these are. Thank you, DEW Drafting Supplies, for still carrying quality products!

Charlie H on Oct 23rd 2021
Was looking for Alvin drafting triangles and found them on DEW drafting supplies. They had a huge selection and the pricing was really good. Shipping was quick and product was well protected. I had ordered from others and triangles came cracked a number of times. I will definitely be purchasing from them again!

Sorry to hear Alvin has went out of business. We orderered a whole bunch of them. DEW was the only one I found online that was well stocked.

DEW always is my go-to for stocking our survey business. No need to look elsewhere when they have such a good track record in the first place.

5 Alvin Drafting Triangle
Wendy on Apr 14th 2021
As an Interior Designer I draw everyday. I use my drafting table and draw floor plans, elevations, renderings and furniture. I use Alvin triangles because they are the best quality. The acrylic stays straight and accurate. And the weight and thickness of the triangle is perfect for continuous use. This particular triangle is translucent fluorescent orange--making it easy to find when there are multiple papers on my drawing table. I also have the florescent yellow/green Alvin triangle but unfortunately the color is discontinued.

Great to have this on hand. Prefer it in most case to the clear.
