Noch Grass Tufts are slightly different to Silflor in that they are made into precise individual tufts protected individually beneath a rigid plastic cover - which means that the chances of them being crushed in the post are massively reduced.
Noch put 105 tufts in each pack and have chosen to make them varied in colour; the Spring pack, for instance, has grass ranging from a very pale yellow-green through to a pale light green. This means that you get a lot more variance in tuft colours for far less money than having to buy 2 or 3 packs of Silflor.
The tufts are in four packs: Spring, Summer, Autumn and a final pack that has three colours of flowering tufts (White, Yellow and Red). The first three packs are £9.50 each and the Flowering pack is £10.50p.
The tufts can be found here and provide a real alternative to Silflor tufts.
