They help keep the tuck cab sticking outward instead of flopping down. **Q: How do you attach the truck cab to your child’s body? Please help we can’t figure it out!!** A: Did anyone figure out how to attach the black straps? **Q: Sizes run small or big?** A: Very big and doesn’t convert easily **Q: I need someone smarter than me to show me how to do the straps on the cab part. How do you secure the straps?** A: Hi! I don’t know if this helps, but my son put on the straps like you would the straps of a bookbag. That’s the only way that helped me to figure it out --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/396859544-optimus-prime-costume-official-converting-transformer-costumes-for-boys-convertible](https://www.desertcart.jp/products/396859544-optimus-prime-costume-official-converting-transformer-costumes-for-boys-convertible) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-22*
