Acrylic keychain file requirements

Please Upload PSD/PNG/PDF/AI file. Please providing CMYK colour. Need 300 resolution, 1000 pixels or more.
The best file to upload is PNG transparent background or PSD format.
Warm Tips : 
①Different design for double side, please separate the layer.
②If your design with semi-transparent part, please separate your design's semi-transparent art from your artwork as an individual layer in PSD file, and name it.
③Charm size should include charms border and hole and depends on the longest edge, not only the printing design size.
