An inexpensive and expendable holder made of a single piece of flexible sheet material such as cardboard or plastic with object insertion openings for frictionally holding in place elongated objects such as test tubes. The insertion openings each comprise a pair of cross cuts penetrating through a top wall surface, and the orientation of immediately adjacent openings sharing a same row or column alternate between “crosses”and “exes”to maximize the number of openings per surface area of the receiving surface while maintaining the structural integrity of the surface. The holder preferably does not include a bottom wall, thereby minimizing the material and cost of the holder.

An object holder made from flexible sheet material and which can be transformed from a flat condition to an erected condition on a horizontal supporting surface and useful for receiving and holding objects, said holder comprising: a horizontal top wall having a plurality of openings for receiving and resiliently gripping objects inserted into the openings, said openings each comprising a pair of cross cuts generally perpendicular to one another, at least some of said openings being arranged in a row, the cross cuts of said openings included in said row being so oriented that neither of the two cuts forming one of said openings of said row are aligned with either of the two cuts forming an opening in said row and located immediately adjacent said one opening; and one or more sidewalls attached to said top wall so as to extend vertically downwardly from the perimeter of said top wall when said holder is in its erected condition and to be engageable with a horizontal supporting surface to hold said top wall in a position elevated from and parallel to such supporting surface.
