PM Import Porcelain Hand Painted Heart Shaped Floral Trinket Box

Covered heart shaped trinket box in a rusty maroon color with colorful hand painted flowers on the cover top.  Trimmed in metallic gold.  In a Noritake 1975 Valentine box, which it fits perfectly but I do not think it is a Noritake piece. There is also a Noritake history of the Valentine Heart card.   Bottom is marked: PM Import with a crown and a number 7.  Condition: One light scratch on top cover, almost looks like it was done when it was made.   

Approximate measurements:  2-5/8" x 2-1/2"   Height: 1-1/8"
