Meiying Kow –
What type of copper is the crimp made of, will it rust over time?
Imran Hanafiah –
Thank you for your question Meiying. The crimp on our Problue SF-401 Copper Double Crimp is made of high-quality oxygen-free copper, which is resistant to corrosion and oxidation. As a result, it is less likely to rust over time. However, to ensure the longevity of the product, we recommend storing it in a dry and clean environment. If you have any further questions or concerns, please don’t hesitate to reach out to us.

Ahmed Lee –
What is the purpose of the ergonomic grip on the Problue SF-401 Copper Double Crimp, is it just for aesthetic value?
Imran Hanafiah –
Dear Ahmed Lee, thank you for your question about the Problue SF-401 Copper Double Crimp. The ergonomic grip on our copper tool is indeed designed with both form and function in mind. While its sleek design may contribute to its aesthetic appeal, its primary purpose is to provide a secure and comfortable hold on the tool, reducing the risk of slippage and fatigue during extended use. Our engineers carefully designed the grip to fit snugly in the hand, making it easier to crimp and other delicate tasks. I hope this information helps you understand the importance of this feature!

I am not satisfied with the minor scratches on the product packaging that made it look used. At the regular price, it should be perfect in condition. The packaging should be improved.

I loved my Problue double crimp experience! It exceeded my expectations. The copper material is top-notch, and the quality is exceptional. The design is ergonomic and comfortable to hold. However, I found the crimp grip to be a bit small for my hands, which is my only minor complaint.
Yusuf Wong –
Can the Problue SF-401 Copper Double Crimp be used for double-barreled shotgun shells?
Imran Hanafiah –
Dear Yusuf, thank you for reaching out to us. Unfortunately, after reviewing your question, I must inform you that the Problue SF-401 Copper Double Crimp is not specifically designed for use with double-barrel shotgun shells. While copper crimps can be used with different types of shotgun shells, we cannot guarantee its effectiveness and safety for double-barreled shells. For optimal results and safety, we recommend using our product as intended with single-barreled shotgun shells. I hope this helps, and please feel free to reach out if you have any further questions!
Xiaoli Yu –
The features I liked about the Problue SF-401 Copper Double Crimp were its reliability and versatility in use. Although it does create a strong crimp, the handle could be a bit larger for better grip.
