silicone, tender. Thank you seller, I recommend...
19 days to Omsk with a track. Quality is normal, metallic cutter. True in Leroy the same 160r. worth it... nevertheless it's too late...
he waited a long time well, all the same typically the order came even no longer hoped for him
It arrived quickly (3 weeks) to operate comfortably, if you plan to repair -- order. The result is much better than smearing with a soap finger))
Got here very quickly. With small diameters is not so simple. Basically, all the same under the standard wine beverages and beer. Itself will not cut, of course. We must enjoy and learn.
