    Avoid contact with eyes. In case of contact rinse thoroughly with clean warm water. For external use only. Stop use if irritation develops. Keep out of reach of children. Store in a cool place out of direct sunlight. Colour and design of actual packs and products may vary slightly from those shown.

  • To maximise closeness, comfort and enjoyment we recommend:

    After wetting your face with plenty of warm water, apply the Daily Face Wash & Scrub to your face (including any stubble or beard) and gently massage in for 1-2 minutes. Thoroughly rinse off with clean water.

    For best results use daily in the morning and evening (and before shaving of course).

    Try shaving in the shower.

    Squeeze shave gel into your palm and massage vigorously into your wet stubble for 30–60 seconds to ensure thorough and even coverage.

    Using a clean sharp blade, shave carefully with short strokes in the direction of your hair’s growth. Rinse your razor frequently.

    Afterwards, thoroughly rinse skin with clean water. Then pat your face dry with a clean towel.

    Using a moisturiser or a balm after shaving helps to soothe and protect your skin.

Rated 2 out of 5 by from Razors Second type of kos razor I've tried. Gillette Mach 3 still easier and more comfortable to use.

Rated 5 out of 5 by from Close and comfortable shave. I bought this mainly because I like it’s retro looking design and wasn’t really expecting it to be particularly good. Imagine how surprised I was to find out that it’s actually a very good razor indeed. Close without being aggressive and easily on a par with anything the big G has to offer imo. One downside is the lack of a rear single blade for those harder to reach areas, I’ve got very used to having one of those and it’s omission here is a mistake I feel. It’s the first ‘cheaper’ razor I’ve found that can easily replace one of the big brands without feeling like a step back in quality. Products supplied with the trial kit are equally impressive and I’ll be a regular user of those too. Give it a go, it’s a cheap way to try something new and I don’t think you’ll be disappointed.

Rated 4 out of 5 by from Perfect Trial Set with Excellent Razor to boot! I've been using KoS Anti-Bacterial Shave Gel for about 10 years. I love the product and the smell - I first used it on a trip to the beautiful mountains of Cyprus and the smell still triggers this memory every morning when I open the tube - an association permanently engrained in my subconscious! Anyhow, I have sensitive skin, have never used soap or skin products on my face other than for shaving as they give me dry skin or spots, but at 55 I decided it was time my skin needed some extra care and the natural ingredients in KoS products caught my attention, so their trial kit was a perfect size and price to evaluate their other products. I got 2 weeks use from these which was long enough to know I love the other products and was ready to invest in the full sized products. The Sensitive Daily Face Wash & Scrub is natural and gentle on the skin with natural wood particles (no eco-damaging plastic micro-beads!) and it caused no dryness or tightness. The SP15 Anti-Ageing Moisturiser is also natural and non-greasy, needs very little to moisturise the entire face and keeps the skin feeling soft and smooth all day. Unfortunately this product is being discontinued but I will try the similar Sensitive Moisturiser in its place and I expect very similar results. I also wanted to start a bulk mail-order shaving plan to reduce trips to the supermarket, reduce cost and waste, so the KoS Eco-Plan kits are my next stop! I did sample the Sensitive Shave Gel as this is currently the only gel available with the bulk 'refillable' option, but while it was an equally good product, it still doesn't beat the smell of the Anti-Bacterial product for me, so i hope they add this option soon. Finally, the K4 razor: I have been using a Mach 3 for years thinking it was good value, but recently the quality of blades has been falling - they become blunt very quickly so only last about 2-3 weeks and I cut myself frequently suggesting the guard quality is compromised. I read great reviews of the K4 but was hesitant about the heavy aluminium 'retro' style handle, however I am really pleased with this razor! The handle is well balanced and a joy to hold, the blades are still very sharp after 2 weeks and there's not a cut in sight. I can shave in 1-2 passes for a smooth finish whereas I did 3-4 passes with the Mach 3. I like that the razor includes a re-usable blade guard for storage, but the plastic suction holder is next to useless and should be removed from sale as it's just another unnecessary plastic product. If you're not already converted to the KoS brand, I recommend this excellent value Trial Set and you won't be disappointed!

Rated 4 out of 5 by from Nice shave Gave a very close shave which i liked. Only negative would be compared the old Azor it's not as bendy and flexible so i cut my self, but maybe just need to get used to the change.

Rated 5 out of 5 by from Great way to try a new shaving kit So glad I tried this trial pack out, I used to love the older versions of this brand but the last few razors did not quite cut it ( pun intended) this has a nice weight and a smooth close cut, Th e face wash is cool and the shaving gel is good but I prefer the KOS oils that I have used forever.

Rated 4 out of 5 by from Nice sample pack. The shaver does not come with any assembly instructions and it took me several minutes to work out how the blade fitted to the shaver. Ditto for the three small white 'rubber' rings. This ties in with today's 'intuitive' world, but does not take into account we are not all smart 20-year-olds. Otherwise all is fine. Customer telephone service is excellent, thank you.
