They are large enough to be visible for audiences of up to a few hundred. The boxes have a complete cover.&amp;nbsp; They are in two different colors.&amp;nbsp; We will presume they are black and red.&amp;nbsp; The magician opens the black box, and inside it is the red box.&amp;nbsp; Obviously the red box is smaller than the black box.&lt;/font&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;font color=&quot;#000000&quot;&gt;&lt;br&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify; &quot;&gt;&lt;span style=&quot;font-size: 20px;&quot;&gt;&lt;font color=&quot;#000000&quot;&gt;The red box is removed, and if you wish you could make a production of silks, spring flowers, streamers etc. from the box.&amp;nbsp; The box is finally shown empty.&amp;nbsp; You now close the black box, put it into the red box, and close the red box. Obviously the black box is now smaller than the red box.&amp;nbsp; This can be repeated as often as you like.&lt;/font&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;font color=&quot;#000000&quot;&gt;&lt;br&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify; &quot;&gt;&lt;span style=&quot;font-size: 20px;&quot;&gt;&lt;font color=&quot;#000000&quot;&gt;Gozinta Boxes work on an ingenious geometric principle, credited to Lubor Fiedler. The boxes are completely solid and rigid.&amp;nbsp; They are not flexible, or elastic, and there are no sliding or moving parts, trap doors, substitutions or any such subterfuges. We supply the set of boxes ready to perform.&amp;nbsp; Boxes are crafted from heavy board, Rexene coated for long life, and supplied complete with instructions at a very modest price.&amp;nbsp; You use your own production items if you wish to make a production from these.&lt;/font&gt;&lt;/span&gt;&lt;/div&gt;
