I saw a post about airtites and thought I would clarify for everyone, as we have been selling them for years.

There are 4 main sizes of airtites used for our hobby, lets call them holders A, B, C, and D.

Holder A is 39mm, just like a chip. This holder is also manufactured with a slightly thinner wall (40mm) and a slightly thicker wall (38mm). This will handle chips that are slightly worn (38mm), regular chips (39mm), and chips that are slightly big (40mm)

Holder B is 45mm, which doesn't fit anything, but with the "ring" can fit the following:

37mm - $1, $2, $7, $28 token
39mm - Chip
40mm - Palms Chip
42mm - Baccarat Chip

Holder C is 47mm, which fits a $20/$40 Silver Strike Directly and the following with a ring:

42mm - Baccarat Chip
43mm - $10 Silver Strike
44mm - $5 token and Palms Baccarat Chip

Holder D is 43mm and is a direct fit for a $10 Strike.

Hope this helps,
Chris
