Absolutely yes, in every way. Our FlexiBell is made by the same manufacturer and has the same quality.

Because we have strong relationships with their supplier and, being a small business, our costs are lower. Also, we want to offer this product at the best possible price.

You can create any weight you want from 12kg to 32kg, except for 13kg and 31kg. If you need those too, you can simply buy a cheap 1kg dumbbell plate (they’re standard size) and use it with the rest. If you’re planning to train with non-standard weights, we recommend this accessory to make things easier: ZeroVibe.

Without a doubt. Both the hex key and the ergonomic key provided make it easy to open the kettlebell and quickly replace the internal weights. You can easily adjust the weight even during your workout, during rest time between exercises.

Absolutely. With the FlexiBell 2 you can perform all the exercises possible with traditional kettlebells and train strength, agility, and endurance effectively.

Of course. Many respected athletes choose our FlexiBell daily for their training and love it. The FlexiBell is well balanced in every weight configuration and never feels bottom-heavy. However, if you compete, we recommend also training with a pair of competition kettlebells at your competition weight, to get even more used to it.

No, it’s not. Just like our hollow ProBalance kettlebells, the FlexiBell handle is shot-blasted for better rust resistance and smoothness. Chalk adheres easily to the surface.

Most of our customers say the vibration is minimal. In some weight setups, a bit of rattle can happen, but nothing dangerous or unstable. If you value comfort and precision, we recommend getting our ZeroVibe to eliminate any vibration in every configuration.

It’s the typical warranty for lifting equipment: it ends when the product is used. We guarantee the FlexiBell 2 leaves the factory free of defects and in perfect condition. It’s a proven product, used for years by top-level athletes and built to last virtually forever. If you throw it at full load into a wall, sure, it may break—and so will the wall. But under normal use, its durability is unmatched. Just hold it in your hands and you’ll see.

Yes, shipping across Italy and Europe is included in the price.

Shipping is included for: Austria, Belgium, Bulgaria, Czechia, Croatia, Denmark, France, Finland, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Poland, Portugal, United Kingdom, Slovenia, Spain, Sweden, Hungary. If your country isn’t listed, contact us to see if we can offer free shipping there too.

We usually ship the FlexiBell as received from the manufacturer. For some European countries outside Italy, we may ship it in two parcels: one with 24kg loaded and another with the remaining 8kg. Both parcels are well packed to arrive safely.

Unfortunately not—saying no is never fun! But we believe the FlexiBell is a top-quality product worth every cent. Our price is extremely competitive worldwide, and you’ll likely find it’s the lowest available for this product.

To ensure accurate information, Kettleblaze does not announce restock dates in advance. We recommend checking our site from time to time and purchasing quickly when it’s available, as demand is high.

Outlet products are FlexiBell 2 units with small cosmetic imperfections—like minor scratches on the top or bottom. They’re sold at a discount or bundled with ZeroVibe for free. The defects are only visual and do not affect safety or functionality.

The FlexiBell 2 is a modular kettlebell, with removable and customizable internal weight plates. You can easily adjust it between 12 and 32kg.

Absolutely. It gives you a full kettlebell set in one piece of equipment, perfect for training at home even with limited space.

The empty shell weighs 12kg. That’s the minimum weight, and you can add internal plates to reach up to 32kg.

Yes, you can use standard 1kg plates with a compatible diameter (approx. 50mm), useful if you want to reach weights like 13 or 31kg.

The balance. FlexiBell maintains shape and weight distribution even with different loads, making it ideal for all types of exercises.

Yes, it’s ideal for beginners too. It allows gradual weight increase and progress over time without changing equipment.

Definitely. Many women choose it for its versatility and fine progression, perfect for toning, building strength, or high-intensity cardio.

Yes, you can remove the plates and pack the 12kg shell in a suitcase. It’s a compact solution for training even away from home.
