I have had the DeLuxeShaving Retro Deluxe brush for some time now and thought I would post some thoughts.
It is a 24mm synthetic knot, set in a two piece resin handle. The handle itself is a great combination of what I would call Bianchi green and black- a nice nod to the '50s. Very pleasant handle shape, the finish also is very "grippy" which I like a great deal. The loft is listed at 50mm, less than some of the others in this category, however the brush itself feels more luxurious than some of my other 24mm synthetic knots.
Sufficient backbone but a very, very soft face feel and generates an abundance of lather as you would expect. I do face lather 100% but feel that it would also lend itself readily for bowl lathering.
Maintenance is a breeze as with other synthetics and it both dries quickly and rinses easily.
For $23 USD I am very happy to have this in the rotation- great performance and the aesthetic has a very cool, retro vibe. Always happy to answer any questions and I did purchase this brush, having no affiliation with Deluxe other than as a pleased consumer.
