Everything is perfect, minus the color bleeding
Style: Purple 3lb Pair
I love the feel of these in my hands, and the color selection! I only give 4 stars because if you have different colors touching (when they’re putting away) the darker colors will rub onto the lighter colors. My light green 5 lbs have stains from the purple 3 lb ones, so now I keep them spaced or out parchment paper between. I have OCD about these things, so it either may not matter to others. But if it does, keep them separated haha.

Light weight and easy to workout with.
Style: Rose Pink 1lb Pair
These small dumbbells are great for bicep curls, triceps extensions, lateral raises, and overhead presses. I cant lift heavy objects so these are perfect for me.

Perfect color, handsize and materials
Style: Lavender 1lb Pair
My physical therapist suggested I use 1 lb. hand weights so I could continue to use them on non-therapy days for weighted movements I did in PT recovering from shoulder surgery. There were many dumbbell brands to choose from, but I'm thrilled I chose this Lionscool brand. The dumbbells/hand weights arrived quickly, carefully bubble-wrapped and zip-tied together so they didn't damage each other (neoprene coating), nor bounce around in transit, plus packaging was strong to support weight of dumbbells. These hand weights come in great colors with weight numbers on the end. I don't feel the neoprene will degrade through use or age. The weights work well and I love the light purple color. I also purchased the 2 lb. weights, and they were packaged identically. The two sets DID arrived separately, which was actually nice if you are limited on how much you can pick up due to my shoulder surgery (I had them shipped to an Amazon locker). It will be some time before I move up to the 2lb weights, but I'm glad I purchased both sets. I would definitely purchase this brand again. I especially like that they are not slick. The neoprene coating covering all of the dumbbell(s) feel a little sandy/gritty, but does not hurt your hand, nor will they slip from your hand accidentally, and six-sided ends. They seem priced similarly to other brands, but since I plan to have these a long time, I figured, why not get the colors-themed sets that I like best, with non-slip weights. (I have 2 and 3 lb. single dumbbells that I purchased at a store which were on sale years ago that are slick, glossy, vinyl-type material colored with end numbers fading off the weights). I prefer these hand weights MUCH more...material, color, shape, and size. I have a larger hand (about an 8), but these do fit my hands fine, and feel secure in my hands as well. Good luck!

Great quality and easy to assemble!
Color: Blues, Size: 56 LB, Color: Blues, Size: 56 LB
I’m really happy with this dumbbell set. The stand was very easy to assemble and feels sturdy once put together. The neoprene coating on the weights is comfortable to grip and doesn’t slip, even when your hands get a little sweaty. I also love the colors—they make the set look nice in my workout space. Perfect for home workouts, compact, and easy to move around. Definitely worth it if you’re looking for a practical and stylish weight set!
