Where can I buy these fasteners?

[Irish Rover]

As may be apparent from the pics, they're on the covers for the drop down screens on the aft cockpit. A few of them seem to be loose and open when it's windy. I'm looking for an online source in the UK or EU.

I wouldn't go that far, I pulled your 3rd picture into Photoshop and adjusted it until the name on the fastener was visible - "PERFIX", then Mr. Google did the rest ..... took me about 3 minutes, but I like a challenge. Glad to be of service.
