Koizumi Seamless Review: A ¥10,000 Five-Blade Shaver vs Panasonic Lamdash Palm-In

This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan.

Quick take

Koizumi's Seamless is a compact five-blade foil shaver for about a third of the price of Panasonic's Lamdash Palm-In, which I have used daily for two years. I shaved one side of my face with each for 30 seconds. The Palm-In felt softer on the skin and maybe shaved a touch closer, but the gap was small. The Seamless is a very good value as a travel shaver.

What I tested

  • Koizumi Seamless, reciprocating five-blade, silver (¥10,532 at the time of recording)
  • Panasonic Lamdash Palm-In, five-blade (¥36,300)
  • Design, cleaning, weight, and a 30-second shave per side

What I found

  • The mirror finish is much shinier than the Amazon photos suggest. It does pick up fingerprints, which wipe off easily.
  • The head pops off with a finger, and with a flat screwdriver you can take the blades apart for an occasional deep clean. Day to day, cleaning is about as easy as the Palm-In.
  • Both are fully waterproof, so you can shave in the shower and rinse them under the tap.
  • The Palm-In's rounded blade head is the likely reason it felt gentler. The closeness difference was marginal.
  • The zippered case closes with a magnet and feels solid.

Who it is for

  • Seamless: you already have a main shaver at home and want a stylish, cheaper one for trips.
  • Palm-In: it will be your everyday shaver and comfort matters most.

Limitations

I shaved once per side and my beard is not heavy, so I cannot say how it handles a heavier beard. Koizumi is a Japanese brand and the Seamless may be hard to find outside Japan. Prices are Amazon Japan prices in yen at the time of recording.
