A die cut tool for applying high or low relief dimensional elements onto a malleable media includes an interchangeable tool head, a magnetic fastening mechanism, and a tool handle. The magnetic fastening mechanism selectively couples the interchangeable tool head to the tool handle. The interchangeable tool head includes an outer cutting blade and a sculpting face. The sculpting face, when pressed against the malleable media, creates high or low relief dimensional elements. The outer cutting blade separates the dimensional element from the surrounding malleable media. The tool handle includes a socket portion and a gripping portion. The interchangeable tool head is securely retained inside the socket portion. The gripping portion provides a gripping surface whereby a user can securely grip the tool handle.

A rotary platform device comprises a rotatable platform; a rotatable annular base disposed at the bottom of the platform. A top surface of the platform has a plane for placing objects, and the platform has an annular first groove; the annular base is disposed inside the annular first groove and is capable of rotating circumferentially along the annular first groove; a plurality of first balls is rotatably arranged at regular intervals on the annular base circumferentially along the annular base, a top portion of each first ball attaches to a top wall of the annular first groove and a side portion of each first ball attaches at least one of two side walls of the annular first groove. The rotary platform device of the present invention enables synchronous guiding and driving of the platform, such that the platform can rotate relative to the annular base more smoothly and stably.

A protective mat is provided which may protect surfaces such as a table top from contact, penetration, or damage from objects or substances such as nail polish and acetone. A protective mat may have raised edge around the periphery to keep spilled liquid from flowing out the mat. A protective mat may contain shapes with raised ridges and recessed middle to act as a well for example in mixing various colors. A protective mat may contain other various shapes for the user to try out various nail art decals or use as a palette for example. A protective mat may contain a ruler and grid to assist a user in designing a nail art decal for example.
