Hasbro is bringing Marvel, Star Wars and Transformers convention exclusives to this weekend’s MCM London – but sky high demand and limited availability means that show visitors will have to be savvy to be sure of snagging them.

Prospective purchasers will need to secure wristbands ahead of time if they want to get their hands on the toy giant’s special convention products – ‘Bumblebee Vol. 1 Retro Rock Garage’ and ‘Bumblebee Gold Volkswagen Beetle Vol. 2 Retro Pop Highway’ from Transformers Studio Series 19 and 20, ‘Red Skull & Electronic Tesseract’ and ‘Defenders Rail Authority 5-Pack’ from the Marvel Legends Series and Star Wars: The Black Series’ Han Solo and Princess Leia.

The company says that wristbands will be given out on a first come, first served basis at the Hasbro stand (N900) from 10:00 am on Friday and 9:00 am on Saturday while supplies last. Each wristband will be distributed per person, per item and labeled with a timeslot for purchasing the product. There will be no wristbands provided on Sunday, however, with any remaining stock being sold from 9:00 am – again on first come, first served basis.

Hasbro’s stand at MCM London Comic Con will be open for product sales from 11:00 to 16:00 on Friday, 10:00 to 16:00 on Saturday and from 9:00 on Sunday while stocks last.

MCM London Comic Con comes to town on 26-28 October 2018. Tickets are available here.
