Spy Pen Set

Fun set of Spy Pens.  Each box contains 2 pens with invisible ink!  The ink is revealed using the light in the pen cap.  Trust me these are such a great way to entertain the kids (and the adults!!). These are brilliant stocking and party bag fillers.

• Each pen uses 3 LR41 Lithium batteries which can be replaced by unscrewing the top section of the pen
• WARNING! Choking hazard, small parts, keep away from children under 3
