Gentleman Jon 3.7 oz. Alum Block in Plastic Case vs Parker Safety Razor's Large Alum Block with Travel Case

We couldn't find enough data on either option to be able to come to any reliable conclusions. We strongly suggest that you look at some alternatives that also cost around $10.

No sources that perform objective hands-on testing have deemed the Gentleman Jon 3.7 oz. Alum Block in Plastic Case worthy of being included in their Alum Block roundups, which typically isn't a good sign.

Taking a look at the Parker Safety Razor's Large Alum Block with Travel Case, we found that it hasn't managed to perform well enough to earn a spot in any Alum Block roundups done by sources that conduct their own, high-quality, hands-on testing. That alone makes it difficult to recommend.

As a last step, we wanted to do a head-to-head Gentleman Jon 3.7 oz. Alum Block in Plastic Case vs. Parker Safety Razor's Large Alum Block with Travel Case comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
