Are the weights themselves solid steel under the neoprene?

The 'brutto'- weight of one 1Lb-dumbbell is Wb = 460.9g. To know the volume I put it in the Pyrex measuring cup with 800mL of water - the water level becomes 890mL (this measuring is not exact but I've what I have) - so V = 90mL One mL of water is 1cm3. I prefer cgs-system (cm - g - sec), not SI. To guess the metal I've to take away neoprene volume Vm = V - Vn. In assessment of geometry I replaced two hexagons with their corresponding circles and all round squares with straight angled ones. I guess neoprene is h=2mm thick including gaps. Vn= ~ h x 4 x (3.14 x D1^2/4) - 2 x (3.14 x Do^2/4) + 2 x 6 x Yo x Zo + 3.14 x Do x Z = 0.2cm x 3.14 x 4.3cm^2 - 3.14 x 2.4cm^2/2 + 2 x 6 x 2.1cm x 1.6cm + 3.14 x 2.4cm x 8.6cm = 0.2cm x 58.09cm2 - 9.05cm2 + 40.32cm2 + 64.84cm2 = 30.84cm3 . The weight of the metal is the 'netto'- weight Wo = 454g. The density is: d = Wo / Vm = 454g / (90cm3 - 30.8cm3) = ~7.7g/cm3 - The Cast iron density is: d(Fe) = 7.87g/cm3. I could congratulate myself with a pretty good guess that the metal inside this 1Lb-dumbbell is a kind of cast iron. Though stainless steel is in the same range but I think they took the cheapest variant. So probably if neoprene is not hermetic enough then the iron inside this dumbbell could rust. I wiped it dry after I submerged it in a water. I don't think that my sweat would penetrate and humidify that iron to rust unless it's already did rust which I doubt. At least I know for sure that it's not lead (Pb) inside. It's not a copper (Cu) alloy which is heavier and much less cheap. Thanks, China!

How can I order the stand alone?

Don’t order the stand. It’s the most terrible design for a stand ever created.

Is the grip on these easy for small hands?

The grip IS NOT designed for small hands. Purchased the 15lb s and had to return bc they aren’t easy to hold. My hand barely closes around them. I don’t want to crush my chest bc I dropped the weight doing presses.
