The Magic Shop offers a wide range of original dice, some geometrical jewelry and a few strange objects.

The dice are from different families like the Average Dice where you must sum the numbers appearing on the top face, the Truncated Sphere Dice, intersection of a polyhedron with a sphere and some other original creations.

The jewelry includes Double Marble Pendant, Dod Earrings and Dod Pendants, Reversible Bracelets as well as some unusual rings.
Finally, some objects are difficult to classify, for example the Hexbox, the Cup Holder or the MegaWireSphere.

Truncated Sphere D33

This is the Regular Edition of the 33-sided die specially designed to be the 33333rd entry of Kevin Cook's dice collection.

It is a big die (diameter is more than 30 mm). The thickness 1.5 mm and the depth of the numbers 0.75 mm.
There is still support material inside so it is also quite heavy...

The numbering has been carefully studied.
All numbers are by groups of 3 that sum to 51:
 - the 3 numbers at the North and South pole
 - the 9 numbers at the equator and at the 2 tropic taken 3 by 3 (any 3 numbers at 120°)
All numbers sum to 34 by group of 2 (except obviously 17, since only 17 itself can sum to 17 to give 34):
 - all the numbers of the poles and of the tropics with their symmetric number relatively to the equator
 - all the numbers of the equator (except 17) with their symmetic number relatively at number 17

Alternative D24 Sphere

This is a Truncated Sphere D24.

This die is inspired by the repulsion force polyhedra. In fact, the underlying polyhedron (not rounded) looks like the two shapes that can be obtained through this technique with 24 points repulsing each others (two Pentagonal Icositetrahedra).
Actually, I calculated the positions of those points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere. The result is a truncated sphere with 24 circular faces of same radius.

See this thread for more informations.

Alternative Truncated Sphere D8

This is another solution for the Truncated Sphere D8, different from the one based on a regular octahedron.

This die is inspired by the repulsion force polyhedra. In fact, the underlying polyhedron (not rounded) is a trapezohedron. It looks like the shape that can be obtained through this technique with 8 points repulsing each others.
But in this case, I calculated the positions of those points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere. The result is a truncated sphere with 8 circular faces of same radius.

This die is made of a shell of 1.5mm that contains support material to make it heavier. The engraved numbers have a 0.75 mm depth.

D50 Sphere

This is a Truncated Sphere D50 based on a special polyhedron that is the intersection of a cube (6 squares), an octahedron (8 hexagons with a 3-fold symmetry), a rhombic dodecahdron (12 hexagons with a 2-fold symmetry) and a non-usual icositetrahedron (24 hexagons with a simple symmetry). You can check: 6 + 8 + 12 + 24 = 50.

D10 with a 4-fold symmetry.

I did this one before knowing about the repulsion force polyhedra, although the shape is the one of the typical result you can obtain through this technique with 10 points : the dual polyhedron has 2 squares and 8 irregular pentagons. I calculated the positions of those points to have a maximal radius for the circles resulting from the intersection of this dual polyhedron with a sphere. The result is a truncated sphere with 10 circular faces of same radius.
It is numbered from 0 to 9. Only 2 faces are opposite one to the other and can hold numbers. The others have edges as opposite, thus the numbers on 8 edges.

This die has an approximate diameter of 24mm and is made of a shell of 1.5mm that contains support material to make it heavier. The engraved numbers have a 0.7 mm depth.

More informations in this post.

The current version has deeper numbers compared to the ones in the pictures (0.7 instead of 0.5 mm).

Truncated Sphere D9.

This is my own interpretation of the D9. Please check also clsn's version.

This die is inspired by the repulsion force polyhedra. In fact, the underlying polyhedron (not rounded) looks like the shape that can be obtained through this technique with 9 points repulsing each others.
But in this case, I calculated the positions of those points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere. The result is a truncated sphere with 9 circular faces of same radius.
It is numbered from 1 to 9: 6 numbers are on vertices, 3 on edges, none on the faces. The sum of the numbers on the upper vertices is 15. Same thing for the sum of the 3 numbers on the lower vertices and the sum of the 3 numbers on the edges. This numbering is closely linked to the well known 3x3 magic square.

This die is made of a shell of 1.5mm that contains support material to make it heavier. The engraved numbers have a 0.75 mm depth. This new version has big numbers that should be easy to read.

Truncated Sphere D17 with a 5-fold symmetry

This die is inspired by the repulsion force polyhedra. In fact, the underlying polyhedron (not rounded) is very similar to the shape that can be obtained through this technique with 17 points repulsing each others.

Actually, I calculated the positions of 17 points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere with the following constraints:
- 1 point per pole (upper and lower face - parallel to the horizontal plane)
- 5 points around each pole
- 5 remaining points corresponding to 5 faces perpendicular to the horizontal plane

The result is a truncated sphere with 17 circular faces of same radius.

For the numbering, as usual:
 - the sum of the 5 numbers of the two tropics and of the equator is constant (and equals to 51)
 - the sum of the 2 poles, of two numbers of the tropics that are symmetric relatively to the equator, of two numbers of the equator that are symmetric relatively to number 9 is constant (and equals to 18)

Truncated Sphere D32, frosted edition.
Based on an idea from Orangery.

The underlying polyhedron is a non-uniform icosidodecahedron (a kind of polyhedral soccer ball).

The distance between two faces is 20mm. The thickness is 1.0mm but it is full of support material to keep it heavy.

It is numbered from 1 to 32 with the difference between two numbers on opposite faces being always 16.
If you take the sum of a face surrounded by 5 neighbours (there are twelve of them, that corespond to pentagons on the underlying polyhedron i.e. before the intersection with a sphere) and its 5 surrounding faces you will always obtain 99.
