A collapsible container, comprising:

• a. a base comprising:
• i. a back side,
• ii. a front side,
• iii. a left side,
• iv. a right side and
• v. a top surface,
• said top surface comprising:
• vi. a back groove located along a whole length of a perimeter of said back side,
• vii. a front groove located along a whole length of a perimeter of said front side,
• viii. at least one left groove located at the perimeter of said left side and
• ix. at least one right groove located at the perimeter of said right side;
• b. a first sleeve having a first set of three flat surfaces:
• x. a back central flat surface as long as said back side of said base,
• xi. a back left side flat surface partially extending along said left side of said base and
• xii. a back right side flat surface partially extending along said right side of said base;
• said back central flat surface comprising a first flat surface extension at a bottom of said back central flat surface;
• said first flat surface extension adapted to be inserted in said back groove located at said back side of said top surface;
• said back left flat surface comprising a second flat surface extension at a bottom of said back left flat surface;
• said second flat surface extension adapted to be inserted in said at least one left groove located at said left side of said top surface, said second flat surface extension being shorter in length than a total length of said bottom of said back left flat surface;
• said back right flat surface comprising a third flat surface extension at a bottom of said back right flat surface;
• said third flat surface extension adapted to be inserted in said at least one right groove located at said right side of said top surface, said third flat surface extension being shorter in length than a total length of said bottom of said back right flat surface;
• c. a second sleeve having a second set of three flat surfaces;
• xiii. a front central flat surface as long as said front side of said base,
• xiv. a front left side flat surface partially extending along said left side of said base and
• xv. a front right side flat surface partially extending along said right side of said base;
• said front central flat surface comprising a second flat surface extension at a bottom of said front central flat surface;
• said second flat surface extension adapted to be inserted in said front groove located at said front side of said top surface;
• wherein said front left side flat surface does not comprise a flat surface extension at a bottom of said front left side flat surface and said front right side flat surface does not comprise a flat surface extension at a bottom of said front right side flat surface;
• wherein said at least one left groove and said at least one right groove do not reach said back groove or said front groove;
• wherein said back right flat surface is wider than said front right flat surface and said back left flat surface is wider than said left right flat surface;
• wherein when said first sleeve and said second sleeve are located in their respective grooves, they completely surround said base.
