is this real Murano?

[lucille]

I purchased this piece at an estate auction and I am wondering if anyone would know anything about this? It is 2 pieces, one seems to fit in the other. You can see small bubbles in it and has the bottom ground. The larger piece measures 10" and the smaller piece is 5-3/4". They both have gold stickers, one says Murano Glassware Crystal Clear Made in Italy with a martini glass; the other sticker says Murano Style Glassware, Crystal Clear Made in Italy.
They are in excellent condition, and the colors are vibrant. Please Help Me!
