The B&M® Transpak is the next step up from the B&M Shift Improver kit.

Lily Clutch - awkward size and fabric.
Color: Spicy, Color: Spicy
The Sam Edelman Lily Clutch handbag is a bit awkward, in my opinion. I've been told that it looks like a taco and like a folded up rug, and it does look rather awkward. It's also much larger and bulkier than I was expecting. I can't even find a comfortable or natural way to hold it. I don't love how it bulges out on the sides or the way it's difficult to grip because of the fabric design.
It's eye catching and a good conversation piece, but it feels impractical. It's more of a statement piece than a useful every day bag or something I'd want to take on a long outing.
It looks interesting, but it isn't a bag that makes my life easier or more compact.

Great boho clutch with lots of interest and texture, but bag itself is small, materials are fragile
Color: Spicy, Color: Spicy
This Sam Edelman Lily Clutch Handbag would be great for a beach vacation or summer getaway. It is very lightweight and almost has a fan-like appearance making it perfect for a hot Summer evening out. I ordered the 'spicy' red and natural color combo, and it looks just like in the product photos. The purse itself excluding the raffia fringe is pretty small and thin, and it does feel a bit fragile. You might be able to fit your phone, a card holder, and a lipstick in there, but that is about it. It is not lined on the inside so it is a touch see through. The magnetic closure is a nice touch and works well, and there is a brown faux leather logo on the outside. It also comes with a dustbag to store it in, which you will want to use since the raffia will easily collect dust and break off easily over time. I do understand that this is a name brand premium item, but it does feel a bit pricey given the overall quality of the materials. I would recommend this if it went on sale at a significant discount.

I think it's large for a clutch,but it's beautiful!
Color: Natural
I ordered this purse because I just love how different and fun it is. I thought it would be great for a sunny vacation. The first thing I noticed when it arrived was that it's much bigger than I thought it would be. The size is mostly in the raffia design. The purse itself is clutch-size, able to hold your phone, credit cards, and some lip gloss. Due to the size of the whole purse, I think it could use an optional strap. The quality and the craftsmanship are top-notch, however. The raffia is amazing, and the colors are very similar to a grass skirt, making it perfect for a tropical vacation or Polynesian-themed get-together.

Taco Purse
Color: Spicy
This might be the silliest bag my wife and I own, but it's definitely unique. I call it "the taco bag," and that's 100000% what it looks like to me. It's a clutch so it's not practical for every day use if you want to keep your hands free, but it has a fun, summery vibe that makes me think my wife would look great in a sundress at a pool party carrying this. Maybe. I honestly am not sure what kind of outfit this bag goes with, but it is exactly as pictured and it feels very well made, which I have come to expect from Sam Edelman. We have several bags by them and they are all lovely, this is the weirdest one and the hardest to figure out where we're going to use it, but I'm not mad I have it and if you like the taco look it lives up to it in person.

Stylish Clutch That Adds a Nice Pop of Color
Color: Spicy
This clutch is such a pretty accessory and the Spicy color really stands out in the best way. It adds a nice pop to an outfit without being too loud, and the shade works well across different seasons. The size is practical for carrying the essentials like a phone, cards, keys, and a lipstick without feeling bulky. I like that it looks polished enough for a dressier event but can still work for a casual dinner out. The material and hardware feel well made, and it has that classic Sam Edelman look that feels put together. It fits comfortably in hand and is easy to carry through the evening. The design is simple but elevated, which makes it versatile. Overall, this is a stylish handbag that feels both useful and attractive.
