Closer inspection shows some of these items to be '3D' etched and particularly attractive. The packet also had a small card with the vendors details on, and without further ado I took myself along to their website to discover a veritable 'Aladin's' cave of scratchbuilding accessories from photo-etched parts to wheels, tyres, motors and bodies. So, I have placed a couple of links below for you to enjoy. Postal service from this seller was very reasonable and comparatively speedy!
