Let’s get on with it! Bring Derek’s double thumbs-up to your tea break with this colourful TomKat gas engineer mug.
The yellow wrap pairs Derek’s catchphrase with a natural-gas tightness-testing reference prompt, including let-by, stabilisation and test stages, plus the TomKat calculator web address.
- White ceramic mug with yellow rim, handle and interior
- 11 oz capacity
- Height 9.6 cm; diameter 8.3 cm
- Printed and dispatched to order by Printful
A fun gift for gas engineers, trainees and TomKat fans. Also available in our cat design.
The printed panel is a reference prompt for trained engineers, not a substitute for the full IGEM/UP/1B Edition 4 standard, appliance instructions or professional judgement.
