L-Boxx dolly casters

[Lime green]

Does anyone know if the casters on the L-Boxx/ Sortimo dolly are the same as the ones on the Sys dolly?  When reading reviews of the L-Boxx/Sortimo dolly people seem to rave about the casters.  From what I can tell, they look very similar and appear to be the same size as the casters on the Sys cart ( newer version).

Sys cart is 100mm / 3.94" > L-Dolly is 6" tall - Acme has '4' as caster size
