Quality of fabric may be less plush.
Size: 50"x60", Color: Tan
Very soft and plush blanket, although it not as thick and heavy as previously purchased in another color (same brand) it’s still a nice blanket.

Heartfelt Gesture of Appreciation
Size: Classic Cozy Collection, Color: "Thank You" Card
The Unboxme Thank You Gift Box proved to be the epitome of a thoughtful and appreciated gift. I recently chose this box as a thank you gift for my mother-in-law, and it was met with genuine delight and gratitude. The Warm + Cozy theme of the box was not just a label; it encapsulated the essence of the carefully curated items within. From the moment she opened the box, my mother-in-law was greeted with an array of cozy delights that radiated warmth and care. The inclusion of quality items, such as a plush blanket, scented candle, and gourmet treats, showcased the attention to detail in selecting items that truly contribute to a cozy and comforting experience. The blanket, in particular, was not just a token gesture but a genuinely luxurious addition that she immediately embraced. The packaging was not only aesthetically pleasing but also conveyed a sense of thoughtfulness and care in the presentation of the gift. The attention to detail in the arrangement of items and the quality of the box itself elevated the entire unboxing experience. What made this gift even more special was its versatility. The Warm + Cozy box is suitable for various recipients, including clients, coworkers, bosses, neighbors, and employees. Its universal appeal speaks to its well-rounded selection of items that can bring joy to a wide range of individuals. In conclusion, the Unboxme Thank You Gift Box for Women, Warm + Cozy edition, is more than just a collection of items; it's a gesture of genuine appreciation and care. My mother-in-law's positive reaction is a testament to the success of this thoughtful gift. Highly recommended for anyone looking to express gratitude with a touch of warmth and coziness.
