2 pairs of right angle magnetic clamps and 2 pairs of magnetic clamps with adjustable angles.

Simply pull apart, place inside and outside your corners and snap into place.

The snap and glue pairs hold the two pieces of plastic, wood, etc. in place and allow you to glue them at the desired angle without further worry.

After curing of the adhesive gently remove the Snap & Glue magnetic clamps.  (Glue not included)
