COSPA has opened reservations for a new line of That Time I Got Reincarnated as a Slime apparel and goods featuring Rimuru Tempest and his slime form. The lineup includes a T-shirt, a thermos stainless steel mug, smartphone cases, pass cases, a towel, a metal carabiner, and two sticker designs. Most items are available for preorder until September 6, 2026, with some sold early at a pop-up shop.
The new COSPA lineup pairs the series' usual character art with practical summer gear. The Rimuru Tempest T-shirt is made for year-round wear, while the thermos mug uses a vacuum double-wall structure to keep drinks at temperature. The smartphone cases come in two sizes and rotate for camera use without removing the device.
Two pass case designs are offered, one with Rimuru Tempest and one with the slime form. The Tem pest diplomatic towel ships wrapped in a special noshi paper. A metal carabiner made in Tsubame, Niigata, holds keys on a ring. The outdoor sticker shows Rimuru sandwiched in a hamburger, and a four-pack mini sticker set uses the same art.
