There's really no substitute for genuine leather, when it comes to durability, strength, longevity, and overall feel good vibes in something as simple as a belt.
If these were knives, the metal would've been sourced in Japan, instead they are belts, with the leather sourced in Italy. Which means belts that will outlast you.
Most of the belts can be made smaller in case you loose all that Christmas weight. See the product page to ensure yours is.
