Plush.

The product is describes
as Ultra Plush. It has no body at all. It does have the plastic barrier, and is very thin. I hope it does not tear during normal body movement while sleeping.

  1. 2-Pack: Thera Rx Stackable Daily Pill and Medicine Organizer
    ★ ★ ★ ★ ★
    Must Have Item

    Must have item whether you travel or just to keep in a purse, backpack or travel bag. Best organization for your daily or weekly pills. I carry my pills with me everywhere, just so I am never caught without. Great price for 2 sets. Don’t hesitate, buy a set for yourself and spread the cheer for a friend that may need a set!

  2. Case Logic Advantage Laptop & Tablet Bag
    ★ ★ ★ ★ ★
    Great Price, Nice Case

    Awesome case, Great Price, very Lightweight. Bought several for gifts. Nothing bad to say about this case. I have a 12” IPad and fits perfectly, with lots of room to spare. Still room for charger, miscellaneous. Items, tablet, pens, pencils. Anything else you may need to take along!

  3. Mibode 5-Piece Electric Spin Scrubber
    ★ ★ ★ ★ ★
    Make your cleaning Easier!

    Glad I bought this Electric Spin Scrubber! Made my tough scrubbing house chores sooo much easier!!! I most dislike cleaning my bathroom, so just found a way to make my worst cleaning chore in the house a whole lot easier! I have 2 large bathrooms and this little gem helps clean both from top to bottom in the amount of time it would take me to clean just 1. WOW, and my hands don’t even touch that disgusting chemicals! Next time this little baby is on sale, do what I did!!! BUY 2, so I am NEVER without 1, You will love it!
