Small and very controllable, this GluePen from Bosch is great for a host of small work where you need to be very precise. Using Li-Ion technology, the built-in 3.6V battery makes it very portable. With rapid heat-up of only 15 seconds (170°C), a single battery charge is enough for 30 minutes (6 glue sticks). It fits comfortably in your hand and works cleanly with an automatic glue retraction. Auto shut-off after 10 minutes. It takes 7mm glue sticks. Supplied with integral 3.6V 1.5Ah battery, micro USB charger and 4 general purpose glue sticks.
