Hi Seval,
Glad to help
urhm, I think Old School Seals only had 1 size. Anyway, I got the Standard seal with birch handle that is 11/8" (3.5cm) wide (which is already slightly larger than some others).
Total cost depends on how many wax sticks u get and whether u get any accessories. $50 - u mean USD right?
A standard seal that uses their inhouse fonts costs US$38. I remember postage was $15. Their faux wax doesn't seem too ex though...
Heheh... sori, I've deleted the (design) pdf Dena sent me.
. I communicated what I had in mind and she designed a couple based on the fonts. Basically, we had our initials made into a monogram e.g. "K & M" The letters "K" & "M" were from the Shelley Allegro font while the ampersand (&

was from Bickley (since having all of them on Shelley just wouldn't fit). Think u'll have a pretty good idea by now
Hmm, faced the same problem on number of wax sticks too. Going by their estimate of 5 seals/stick, u should be safe with 50 sticks i.e. 2 boxes of 38 each ($12 in total). I ordered 2 different colours cos I'm thinking of mixing the colours heheh...
How I'm gonna do that is to melt the colours in a little bowl over a heat source, then use a spoon to pour the faux wax mixture onto the surface. This is similar to Custom Wax n Seal's Melting Pot. Dena said this shouldn't be a prob so let's see....
But if u wanna stick to 1 colour, then a glue gun will be a good investment. I believe u should be able to get the glue gun in SG (e.g. Bras Basah) where it'd be much cheaper (chk the dimensions first though). IMO, dun worry about getting a little bit extra because there'd always be Christmas or New Year cards to send.
Phew, I hope I've answered all your questions. Feel free to ask anything else. Fyi, here's another site for your consideration
