This is the thinnest casein tri we've ever offered with grip holes. I believe it's the thinnest in the industry with that feature. At only 1.15 mm thick (1.10 - 1.20 mm, hand finished thickness), we expect this to be a very popular model once word gets out. As with all our products, it's precision machined, cut and finished, then hand tested in our 100% quality control department before leaving our building. And it comes with FREE SHIPPING!
