I know. I actually bought a pair of dumbbells made in Korea. Soft vinyl is
problematic because one is unable to fill to capacity; as soon as you fill
it up (which is very cumbersome) water pours out as one tries to insert the
plug. Rigid plastic would not have such a problem.

Interesting idea, but there are already companies that make and sell
water (water fillable) weights for travel, sometimes called portable
weights or aquabells. They are usually made of a soft vinyl, like an
air matteress, much cheaper than blow molding a hard plastic. Obviously
they already have the technology to do it. The ads I have seen say
things like "fill to whatever weight you want, up to 16 pounds" or some
other customary unit, but I only looked at a couple of US website

Subject: [USMA:54001] Water Bottle Dumbbell Weights
Does anybody know about a company that could manufacture the item I
describe below? I have sent the message below to several bottle
manufacturing companies, but so far, they all say they cannot help me. I
think Water Bottle Dumbbell Weights would be a great way Americans can
learn a relationship between volume and weight. I would appreciate any
ideas you send my way. Thanks.
I have an idea and perhaps you can help. I want plastic water bottles in
the shape of dumbbell weights (in metric-only units) with my company
name (MetricPioneer.com). Ideally, the fully functional dumbbell weights
would be empty so one could fill them with water, for example four
liters of water makes a four kilogram dumbbell (4 L water = 4 kg
weight). I would consider smaller sized Water Bottle Dumbbell Weights,
perhaps 3 L / 3 kg or even 2 L / 2 kg sizes or even a 1 L / 1 kg size.
Please give me a call and let me know if you can customize this product
for me. Thanks.
