Internal dimensions are approximately 6.7 inches tall × 5 inches wide × 4 inches deep (about 6.7 in × 5 in × 4 in).
Descriptions list an acrylic frame combined with an ultra-clear, impact-resistant hard plastic body.
They offer rigid, impact-resistant construction to prevent warping and corner damage; protect contents from dust and moisture; guard autographs against smudges and scratches; and limit UV exposure.
The beveled-edge, flat-top design lets multiple cases stack neatly without sliding — each case can lock onto the one below for space-saving display.
The box measures about 2.4 inches high × 5.3 inches wide and is described as roomy — it can hold up to about 60 pens or pencils and also fits markers and crayons.
Available as straps or pop-socket styles, the grips provide a secure hold, reduce hand fatigue during extended use, and keep the device slim and lightweight for easier one-handed reading.
Strap styles are offered in black, blue, and white; pop-socket styles come in shapes such as heart, star, and bow.
The box is made from EVA and is described as easy to clean; it can be machine washed on a gentle cycle.
