HPL=High Pressure Laminate,it is one type of panel,it is widely used for toilet partitions,lockers,benches and so on.It is a high-quality panel compared to traditional wood for its impact resistance,waterproof,wet resistance,etc.What is more ,its thickness could be customized from 2mm to 25mm.I heard a nice corporation Jialifu on the Internet,you could check it if you need.

I don't know, the only ones I know of are Evite.com, Vistaprint.com, Shutterfly.com and Kodak or Kodakgallery.com. You can probably also do that at drugstore websites like Walgreens.com and CVS.com if they even still have a website and if that is still the current address.
