a second indentation located between the second lower groove and the second end wall in the flange of the basket;

a first protuberance located adjacent the first upper groove on the lid and in alignment with the first indentation; and

a second protuberance located adjacent the second upper groove on the lid and in alignment with the second indentation;

wherein the first indentation and first protuberance are mated when the lid is mated with the basket;

wherein the second indentation and second protuberance are mated when the lid is mated with the basket.

10. A container for holding goods comprising:

a basket having a base and a sidewall extending from the base to a flange, the sidewall having four faces, the four faces including a pair of end walls, a front wall and a back wall;

a lid, having an upper flange, mateable with the basket;

a first sawtooth structure formed within a first end wall of the pair of end walls, the first sawtooth structure comprising a first set of at least three concave grooves integrally connected by a first set of ridges, the first set of at least three concave grooves comprising:

a first pair of outer grooves; and

an inner groove integrally connected between the second pair of outer grooves by the second set of ridges;

wherein each outer groove of the first pair outer grooves includes a first outer side portion extending upwardly to a top portion of the flange and a first inner side portion extending upwardly to the first set ridges; and

a second sawtooth structure formed within the lid and substantially minoring the first sawtooth structure when the lid is mated with the basket;

a third sawtooth structure formed within a second end wall of the pair of end walls, the third sawtooth structure comprising a second set of at least three concave grooves integrally connected by a second set of ridges, the second set of at least three concave grooves comprising:

a second pair of outer grooves; and

a second inner groove integrally connected between the second pair of outer grooves by the second set of ridges;

wherein each outer groove of the second pair outer grooves includes a second outer side portion extending upwardly to a top portion of the upper flange and a second inner side portion extending upwardly to the second set of ridges; and

a fourth sawtooth structure formed within the lid and substantially mirroring the third sawtooth structure when the lid is mated with the basket.

11. The container of claim 10 , wherein the first sawtooth structure and the second sawtooth structure form a first opening that generally resembles a first string of beads; and wherein the third sawtooth structure and the fourth sawtooth structure form a second opening that generally resembles a second string of beads.

12. The container of claim 10 , wherein the first set of ridges are located below the top portion of the flange; and wherein the second set of ridges are located below the top portion of the upper flange.

13. The container of claim 10 , further comprising:

a first finger-hole having a first upper groove in the upper flange and a first lower groove in the flange; and

a second finger-hole having a second upper groove in the upper flange and a second lower groove in the flange;

wherein the first and second finger-holes are formed when the lid is mated with the basket;

wherein the first and second finger-holes are separated by a front portion of the flange.

14. The container of claim 13 , further comprising:
