What each material is
The Jetec example is a pack of clear acrylic discs: transparent, with smooth edges and a protective film on both sides that the listing says to peel before use. The listing calls them reusable blanks and names coasters, Christmas ornaments, keychains, place cards and other small craft pieces as uses.
The Anpuimult example is a pack of self-adhesive cork sheets sold as coaster bottoms and backing sheets. The listing describes a soft feel, a non-slip surface and no odor, and names DIY coasters, tiles, footpads and wall tiles as uses. Where the acrylic discs are a clear face, the cork sheets are a soft backing.
Size and shape
The acrylic discs are sized at 3.5 inch in the title and the size field, and the pack holds 30 pieces. The spec table’s dimension figures do not match a 3.5 inch disc, so the title and size field are the safer guide to the disc size, and the listing states no thickness.
The cork sheets disagree with themselves on size: the title says 4″ x 4″, while the bullets and the spec table give 3.74″ x 3.74″. The bullets give a thickness of 1mm, while the spec table gives 0.1 inches. The pack holds 100 pieces, so the cork side is the bulk buy of the pair.
Working with them
On the acrylic side, the work is peeling: the listing says to peel off the surface protective film on both sides before use, leaving a clean sheet. The discs are listed as reusable blanks, and the listing names drawing boards and graffiti work among the craft uses.
On the cork side, the work is sticking and shaping: the sheets carry a strong adhesive backing, the listing says they can be cut into any shape, and the cork surface can be written on with a marker for a unique pattern. Neither listing states laser settings or machine compatibility, so check the machine guidance for the material before cutting or engraving.
