Great holder for standard tissues on dash
Color: Black, Style: 1 Pack
This fits very well behind my Rave4 map display. Just drop standard tissues into the box and refill as necessary.

Celebration of Life
Color: Black, Style: 1 Pack
I bought this to put on the memory table for a Celebration of Life service to hold 100 jet black ball point pens with FOREVER IN OUR HEARTS printed in white, the pens being for attendees to keep after they signed the guest book with them. This box was perfect.

It’s pricey
Color: Black, Style: 1 Pack
Ridiculous price for a plastic tray but it was the right size for my center console in my SUV.

Neat and Square
Color: Black, Size: Square
This turned out to be durable and looks good on my valet table. The difference in the way it snaps to the sides, keeps the corners square and looks better than the other models that force the corners to extend outward.
