They have a matte top/front and a gloss back/bottom. Our default side is the Matte Side. 

Some pieces may arrive with blue writing across them - this is not on the acrylic but is on a plastic film that you will need to remove to reveal the Matte side

Material Thickness: 3mm (thickness varies up to 1mm either way between batches)

Advantages:

• Acrylic is opaque making it perfect for hiding glue on findings like post pads and brooch pins.
  
• Cuts well and leaves a clean, smooth edge line that shows the core colour on the side edges.
• Smooth Gloss Surface one side and Matte on  other side.

• Comes with a protective tape coating that will need to be peeled off.
• Thickness can vary by  to 1mm as a result of the manufacturing process which can make layered pieces inconsistent in height.
• Is difficult to capture colour correctly; allow for slight variations from monitor to actual item when received.
