Sandbox Card Frames

Sandbox Card Frames is a set of 11 card, currency and notification components drawn in the voxel style, where each surface is the front face of a cube with a lit top face and a shaded right face. It contains four rarity card frames, three currency counters, a notification badge and three toast banners.

Rarity is almost always encoded as a border colour, which fails twice: it disappears in greyscale, and it competes with the item art, which is itself coloured. This set encodes rarity as structure instead.

The extrusion is real geometry rather than a shadow: the light angle never changes, there are exactly three tones per block, and the front face is inset so the cube stays inside its own sprite bounds.

Inside that style this is the Sandbox reading of it: a light interface on a desert tan palette with sky blue accents, built around a header band across the top of the frame, chamfered buttons at 112x40, banded bars divided into 12 segments, and two-tone icons on a 16px grid. Those measurements are why two families can share an art style without being interchangeable: the style decides how an edge is drawn, the numbers decide what the interface is for.

Each tier adds a countable feature — common has none, rare adds two corner brackets, epic adds an inner rule and four brackets, legendary adds a crown band. You can tell them apart at thumbnail size, in a screenshot, and with the colour removed. The toast banners keep colour to a 6px edge stripe so the message text sits at the same contrast in all three tones.

Every sprite ships as an editable SVG and as transparent PNG at 1x, 2x and 4x, so you can drop the PNGs straight into an engine or open the vector and change a colour. Built to the same measurements as the rest of the Sandbox family, which means this kit and the Sandbox panel kit line up without either being resized. A good fit for voxel and blocky games.
