TPU inner tubes

I have some brand new and boxed TPU inner tubes that I'd like to sell. I have 4 tubes with 85mm valves and 2 with 65mm valves.

These are effectively the same as Tubolitos, Reveloop or Pirelli smart tubes. They are sub 40g, apparently twice as puncture resistant vs butyl, improve ride comfort and offer very competitive rolling resistance against latex and tubeless. They are basically a great value upgrade or an ideal spare tube given their compact size.

Looking for £12.50 posted. Collection/meet somewhere is possible if London based (I'm in TW12)
