OK4U2 Perfume for women

a clear bottle about 7 inches tall with a white over cap about 5 and half inches tall. no markings on bottle, but OK4U2 near bottom side of cap and the U2 is cut out in the cap to show color of perfume. Top of cap is slightly domed. Would like to buy with the box that shows manufacturer. I do know it is not a famous maker like the expensive brands. Thank you for any of your help. I did see one on e-bay awhile back but neglected to buy it.
