Must buy for traveling
Color: Pale Rose, Size: 60.00" x 30.00"
Bought two of these towels for our trip to an all inclusive in Punta Cana, DR. I totally loved these towels and I wish I would've bought them before. This towel is super light weight and easy to pack. I bought the biggest size available and it was perfect. They dry very quickly and very convenient to use. It is not the typical towel so when you use It the first time it feels a little weird but you will end up loving it. It dries your body very well. It has a little loop that you can use to hang it so it can dry. I am 5'0 and couldve done the 24x48 size but I went with the 30x60 for both hubby and I.

Great towels!
Color: Navy Blue, Size: 40.00" x 20.00"
I absolutely love these towels! I bought them while living abroad and they lasted me for the entire year and a half and were the perfect packing size. I also love that they offer different sizes. Machine wash, easy to pack, soak up lots of water for such light weight and thin material.

Great for my lawn chair! Must have for the summer!
Color: Gray, Size: 40.00" x 20.00", Color: Gray, Size: 40.00" x 20.00"
I got the 40x20 in the grey and it fits perfectly folded in half for my chair! I get so sweaty so this helps keep it at bay. The little button clip is nice so it doesn’t fly away. The grey just matches perfectly! Lightweight & dries quickly. Perfect for the hot summer days at sporting events. Already recommend to my family members!

Great product for little money & easy to use.
Size: 7.9"
This is a great screen protector. It came with everything needed to apply it and it was extremely easy to put on. The included frame helped with putting on the screen protector perfectly and I didn't have any bubbles or dust, in fact I can't even tell it has a screen protector because the clarity is flawless. The screen protector fit perfectly. I'm extremely happy with my purchase and I will only buy from this store from now on. I highly recommend buying your screen protector from here.
