I have checked out your interesting site SB. You are clearly the man to go to for sellotape; I don't think, given my intended purpose that the Chinese 'whiffy' tape would be a problem. What's the bottom line on the whiffy tape?? Does it come in big rolls like gaffa tape....obviously that would save a lot of time. And better still, can you get it in double sided version???
That's what I love about this site; the expertise, the collectors of all things interesting and unique. If I might also mention, if this Chinese tape is a collector's item, again, bearing in mind its intended purpose, a cheaper alternative would do.
