Reviews

  1. 2-Pack: Mikasa 4-inch Blow Out Flameless with Candle Rings
    ★ ★ ★ ★ ★
    Awesome

    Candles were exactly as advertised. I am very happy with them

  2. Uskrige Premium Cooling Mattress Topper
    ★ ★ ★ ★ ★
    Premium Uskrige Cooling Mattress Topper

    I love the cooling mattress topper because it is so soft and comfortable.

  3. Steeltime Unisex Genuine Leather Serenity Prayer Crossbody Bag
    ★ ★ ★ ★ ★
    …and the wisdom…

    I’ve never seen anything like it! Having the reminder of the words I’ve recited a million times on a medium that will be with me as I step out the door is priceless. The quality is very nice and the pebble leather attractive. This will be a great gift.
