NATROSESBlue Preserved Roses in a Box That Last Up to 3 Years, Long Lasting Roses Gifts for Her,Valentines Day Gifts, (Blue)

What preserves the roses?

Can you remove individual flower out of the box?

Do these maintain any of their scent?

I want to order a lot more as gifts for mother’s day. want to get order soon. is it ok to keep them in the closed packaged boxes unopened for months?
