Buy a different one
Color: White
It looks nice but the trimming is garbage. The smaller trimmer l like for eyebrows or close shaving facial hair is worthless. You cannot get close enough nor can you see what you’re doing. You also cannot get right on the edge for precise edges for eyebrows for instance because of how it’s made.
The seller does not allow for simple drop off returns either. Too much of a hassle to print labels and too costly for ups pick up. A waste of $20.
Buy something else.

Great Product
Color: White
I’m honestly really happy with this purchase! This 3-in-1 bikini trimmer came exactly as expected and works super well. It’s easy to use, lightweight, and doesn’t feel cheap at all. I like that it comes with different attachments so you can switch it up depending on what you need—that’s a big plus.
It trims smoothly without pulling or irritating my skin, which was something I was worried about, but it handled everything gently. The design is cute and simple, and it’s easy to clean after using it too. For the price, it’s definitely worth it—you get good quality without spending a lot.
Shipping was on time and everything came in good condition. Overall, I’d definitely recommend this if you’re looking for something affordable that still gets the job done right!

Very good toothbrush that your cat can chew to help clean his teeth
These are silicone pet toothbrushes. What they work really well for, is letting your cat chew to clean their own teeth (once you put some tasty fish toothpaste on it). It's so difficult to find things the cats will actually chew on in this way and the fact that its silicone (soft but not easily broken) is perfect. I recommend just holding the other end and encouraging the cat to chew on the silicone part, while adding toothpaste as needed. I've only convinced one of my cats to do this, but he loves it! I use a different smaller and softer brush to actually brush with and combined, this seems to be making a big difference for the plaque and his breathe. Very happy I found these and will repurchase as needed.

Makes brushing my cat's teeth easy!
My cat loves this brush 🪥 I like the 360 degree bristles which for my pet are the right texture to keep their teeth clean and healthy. Good price get 2 plus the extra holder is cute

Brush is great, fish not
My cats use them great and I love how it’s a 360 brush bc they bite it better. They are deep too so you can really squish the toothpaste in them. Easily to clean. The little fish that’s supposed to hold it to the ground doesn’t work well at all though, it just flops out. Love that they all have a case to go in.
