Good looking
Color: Retro
This is a good looking box keeps everything nice in one place. Unfortunately, you have to get the 2 inch box high of tissues because if you get the larger box, it doesn’t fit by 2 cm they made the box exactly the size of the tissue box which means no room to close it, so you have to Buy the tiny boxes of tissues. Which is a bummer.

Does not fit Costco size Kleenex boxes
Color: Black
I use this holder exclusively for loose tissues. Do not order this if you want to use it with the Costco size tissue boxes, they won't fit. This fact doesn't bother me though, because I have other tissue holders for that purpose. Sometimes when the Kleenex box is getting low, taking a tissue does not reliably pull out the next tissue with it. To avoid this, I throw away the box and then interleave the loose tissues together with those already in this holder. That way i can put a full box of Costco tissues in my other holders and have problem free access to the previously troublesome tissues. I also really like the storage compartments that are built into this holder. They are very handy for remote controls, lip balm, ponytail holders, etc.

Organizer’s dream.
Color: Black
I love this thing. Had a smaller version of this for 5 years. I ruined that one accidentally. This one is a bit longer and higher. It holds full size Kleenex brand Ultrasoft tissues without the box. Did not try it with the box. Holds pens, pencils, 6” ruler, 2 sets of glasses and looks great while doing just that. No smell, sturdy, and worth every penny.

Great Tray For Storing My Everyday Carries
Size: 8.5" x 5.8" x 1.9", Color: Black
My everyday carry items (wallet, keys, etc.), used to just get thrown around wherever when I'd get home, but this little tray makes a great, defined, space for me to keep those things when I don't need them on me. The soft lining reduces the obnoxious sound of throwing keys on a hard surface, and of course keeps me from scratching up a surface. The build feels quality and I haven't seen any damage to it yet. Also the all black version with gold buckle looks quite good and adds a subtle touch of luxury. Absolute recommend for the price.
