Blue cap ...
The most recurrent question i have received from people reading my posts about fixing lenses was not about cold cream (surprisingly), but about the sink cap i use for removing the front ring of the lenses i service (it works like a charm for front rings from 36 up to 58mm) ...
So, after shipping several to some of my Flickr contacts in the US, i decided to read the cardboard of the packaging, and discovered that the cap is manufactured by Wirquin Innovation ...
A little googling pointed me to their web site here, where i located the cap in the Wirquin-dedicated page, in the Drainage section (it is named "Universal Plug") ...
Hope that this post is useful to someone ...
The company seems to have both European and Australian distributors, so, with a bit of luck, other people interested in it should be able to find it easily ...
