[sash11]

Hi guys i just wanted to know wat is the difrence betuine spider ben and an i.t.r.

realy confused..:confused:

[magick]

the spider pen is an electronic invisible thread reel (I.T.R.)


but i.t.r.'s come in many shapes and sizes.......and not all are electronic.

[traumatised-magic]

like magick said its an ITR but it has a small motor inside so it retracts the thread electronically, where as standard ITR make use of elastic to wind the thread back....i would assume ur thinkin of gettin one, if u think the spider pen is good, u should prob wait a littel while for the tarantula wich is suposedly an upgrade to the spider pen
