A nice snack
These are just salty enough, easy to pack, have a good taste and satisfy my need to crunch. They have a decent flavor too. I like them.

Very disappointed
I was really excited to receive these snack packs as someone who recently is doing keto. I was very disappointed that they have no flavor, not lightly salted or anything and were almost stale/soggy. Keto stuff is expensive and I’ve found some good nut mixes before, these just are not it and maybe sat too long?

"OK" taste
I was excited to try these but was disappointed when I did. They are "OK" taste wise..no bold flavors that is for sure. They will be nice on-the-go to throw in my purse but I wouldn't buy them again - not only because they taste rather bla but also because they were a but expensive.

Great value, great product!
I use this as a home jewelry box - I don't wear a lot of jewelry, so it fits my needs perfectly. Its pretty lightweight and would be good for travels as well. The outside is leather-like and seems to be waterproof so far. I use the first layer for jewelery and second layer to store my hairclips and pins. I've had it for a few months and it seems to be great quality and durable! Definitely a good value as well because I've seen similar jewelry boxes sold at popular retail stores for over $30.

Lovely Slate Gray Jewelry Box
I just received this Slate Gray jewelry box. It's really quite lovely and just the right size for my granddaughter's vanity. I'm really excited about giving it to her, for her 12th Birthday, to hold her better jewelry. It's so nice I'm going to order another one for my other Granddaughter's Birthday.
