Items will be shipped as briefs only. Thank you for your understanding.*** Based on data and technology accumulated from traditional boxer briefs, we have achieved a free size tailored to children's body types. This is a new sensation in kids' underwear, suitable for children aged 5 to 12. BETONES boxer briefs offer exceptional stretchability. Using a 3D knitting machine from Santoni, a company from the clothing kingdom of Italy, we create "3D Knit Boxer Briefs." As a result, we have achieved a design that is as seamless as possible. "Seamless" means fewer seams. What's good about seamless is that "stretchability dramatically improves." No matter how soft the fabric is, the stretchability inevitably worsens at the seams where fabric is joined together. That's why seamless (fewer seams) dramatically improves stretchability. The result is the first "one-size-fits-all" in the boxer brief world. With calculated sizing and molding technology, this brand has achieved free-size boxer briefs that fit any body type. 【Color】 Emerald, etc. 【Size (Label)】 Manufacturer Recommended Size: Waist 48-60cm (Approximately for elementary school students, grades 1-6) 【Actual Measurements】 【Material】 Polyester 60%, Nylon 30%, Polyurethane 10% 【Condition】 New, Unused
