Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4451208. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed to fit the 2003 Chevrolet Venture, 2003 Buick Rendezvous, and additional vehicles. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to be certified by CARB for legal use in CA/CARB restricted states for the listed vehicles.

Great for face and body. Natural and smells great.
Scent: vanilla orange, Scent: vanilla orange
Great Soap. I spend about $75 for spa quality face wash because of my skin type but this works better and even calms my skin better. It smells great and can be used on the body and face. My skin loves it. I’m a customer for life.

great bar soap
Scent: eucamint
I like this bar soap. It lathers, cleans, and rinses effectively and does not dry out my skin. It exfoliates lightly. It's a decent size and shape bar that makes it convenient and easy to use. The package count is a reasonable 3 bars and the packaging in minimal. Its a well made bar of soap. And its plant based and natural. The scent smells great and is subtle and not perfumy. I'm a guy and this soap is great for me. I have long been on a quest to find a bar soap that doesn't dry out my skin and has a scent for a guy without being a stupid scent like burned wood, leather, tobacco, etc. Plus the bar shouldn't be so big and heavy that its difficult to use, to store, or breaks your foot if you drop it. I also don't want to have to buy 12 bars at once nor should it be super expensive. Plus has to be natural and biodegradable. I found a brand and bar that did all that and used for a number of years, but then they stopped making it. So, I went on a new quest of many different bar soaps and when I found this one, it checked all the boxes and expect it will be my new ongoing bar soap for years to come.

Great quality Soap
Scent: Oatmeal Shea (Unsented)
This natural bar soap is absolutely fantastic! I’ve purchased it multiple times now, and it has never disappointed. The quality is consistent with every bar — it lathers well, cleans thoroughly, and leaves my skin feeling fresh without any dryness. I really appreciate that it’s made with natural ingredients, and the scent is clean and refreshing without being overpowering. It lasts a good amount of time, making it a great value as well. Overall, this is a high-quality soap I keep coming back to. The fact that I’ve bought it multiple times says it all — it’s reliable, gentle, and one of the best natural soaps I’ve used. Highly recommended!

Sometimes Size Does Matter
Scent: Alpine & Spice, Scent: Alpine & Spice
Let me just get this out of the way now the soap itself smells decent, nothing wrong there. I only wish I got another cent. Not that this one smells bad it’s just it wasn’t my cup of tea. I’m mostly disappointed about the size because I’ve been through this before. The soaps themselves are not big enough to fill out the box as you can spot in some of the pictures and video. I honestly feel like the soap size was different in the pictures of the customer reviews that I saw. Each bar may last me a week and a half and that’s with a soap saver. To be honest, the box that it came in would fit two decent size soaps if they filled out the box.
