All Aluminum caps vs plastic top caps. Do they look bad?

[MrTexas2]

So my Kebby crimper is 10 years old and has a little rust. Therefore I bought a new one. Got is for a good price, $201 off Amazon.

Unfortunately I waited 2 months (time for a new batch of test) to use it, and found out that it only works with single piece all aluminum caps. I missed the Amazon return window. Normally I use aluminum caps that have the plastic lids. This is for 10 ml bottles.

What do you guys think of all aluminum caps, do they look unprofessional?

I just found this post which suggests that all aluminum is superior especially in terms of preventing contamination:


Aluminum vial caps offer several advantages over plastic ones, making them a preferred choice in pharmaceutical and packaging industries. Their superior durability ensures a secure seal, preventing contamination and leakage. Unlike plastic, aluminum is non-reactive, maintaining the integrity of sensitive medicines and chemicals. Additionally, aluminum vial caps are tamper-evident, enhancing safety and regulatory compliance. They also provide better temperature resistance, making them ideal for sterile and high-precision applications. Most importantly, aluminum is 100% recyclable, supporting sustainability efforts and reducing environmental impact compared to plastic alternatives.
