Thank you very much, Frank. The second set seems much more useful for
ceramic tubes that have maximum seal temperatures up to 250C (482F), and
there are also twice as many crayons for half the price (really? that
seems too good to be true!).

Can McM-C handle foreign mail order without being hit for small order
charges, import duty etc etc?
