This week's new product is the Glue Looper.  According to their website, the Glue Looper
is "a micro glue applicator made for applying a VERY small amount of LOW VISCOSITY  
(i.e. - very thin) glue where you want it to go with very little or no trace of the glue."

I've ordered mine and with just a first look it appears to be very well made.
