Tea Pot Box

Reference:

. .

Dimensions are measured inside from the edge of soft padding which means there is a still space when being squashed. With grey and brown boxes could be extended to 100 x 100 and red one to 95 x 95 (mm) . You can squeeze in bigger than that
, but then soft protection is not that effective and there is a much higher chance of your teapot being damaged.
