HALTZ 2 Pack Door Stoppers for Floor (12 x 3.6 x 2 cm) – Heavy-Duty Door Wedge – Non-Skid & Scratch Resistant Door Stop, Durable Rubber Door Stopper – Ideal for Floors, Carpets, Tiles & Wood (Grey)

These are rubber and flexible. I am a cleaner and these are really good. If you need a bigger stop just double them up. They don't leave marks on laminate floors or tiling floors. I use mine so many times a day I have lost count. They are holding up well. They are worth the price. I even bought some for my work colleague's and they like them .

Very good product especially for doors with small gap under. Solved our problem with our cat closing our doors unintentionally while we are away. Plastic ones was always causing issues.

I was initially a bit disappointed with these as they seemed a bit flimsy, but in use, they are significantly better than the one I needed to replace: Mainly because the wedge end is much thinner than my old ones, so have fitted even the tightest of does. So a 'thumbs up' from me.

I like these rubber door stoppers the don’t slip away on heavy doors and grips well on the surface to hold back the doors

Great product and price. Perfect for stopping the doors from closing.

As above

Bought these for my work place , where previous black door stops were marking the floor. So far no marks and fit under the door perfectly.

Really good and non slip, good quality product
