James Tredwell returned figures of 4-22 as Kent claimed a comfortable seven-wicket victory over Holland in Deventer.
The hosts were bowled out for just 101 after being put in to bat, with Kent chasing down the meagre total with more than 16 of the rain-reduced 39 overs to spare.
The Netherlands did have them in minor difficulty at 59-3 but Kent had more than enough to get over the line as Brendan Nash scored an unbeaten 45.
Sam Billings (7) had been the first man down for Kent, holing out off Paul van Meekeren, with the same bowler then removing Rob Key for 16 in the tenth over.
Van Meekeren (3-42) was the only man making inroads for the Netherlands and when he got rid of Darren Stevens for 11, his side had an outside chance. But the rest of the attack could not build on his good work as Nash and Ben Harmison (17 not out) saw the job out.
A clinical display with the ball had earlier put Kent in complete control, with the home side, who had only four batsmen reach double figures, reeling on 6-3 at one point.
Eric Szwarczynsk (1) went after seven balls, hit on the pads by Matt Coles, with Wesley Barresi (0) short of his ground and sent back to the pavilion six balls later and Tom Cooper (2) caught behind.
A revival of sorts got them to 40 when Daan van Bunge (18) was cleaned up by Tredwell, who also snared Dom Michael (20) and Peter Borren (6).
Tom de Grooth got to 18 before falling to Tredwell (4-22), while Pieter Seelar top-scored with 26 to help his side reach three figures.
