The Oliver 1kg dumbbell is on a flat surface more comfortable to grip than the Reebok.
For the handle of the dumbbell 1kg Reebok is long enough for wide hands. The Oliver dumbbell is total as long as the handle of Reebok.
Reebok is relative more expensive because the price does not apply to a pair.
Incidentally, the vinyl material dissolves as laser printout from the paper, the letters then stick to the dumbbell.
