Plush mini Grinches are typically made from polyester. Collectible mini figures and kits often use plastics such as polypropylene and ABS.
Age labeling varies by item: some listings show "All Ages," others list "1 Year and Up," and the collectible DIY kit is labeled "8 Years and Up."
Care instructions on multiple listings advise spot cleaning or wiping clean rather than full machine washing.
Several listings note compliance with ASTM standards. The collectible mini kit also carries a CPSC choking-hazard warning because it contains small parts.
Weights vary across listings, from about 0.05 pounds up to 3 pounds; several items show typical weights around 0.17–0.2 pounds.
Many palm-sized plush descriptions note they contain bean pellets (or similar bean-filling) to add weight and help the plush sit stably.
Collectible kits are made from plastics like polypropylene and ABS and are labeled for older children (e.g., "8 Years and Up"). Plush versions use polyester and are often labeled for "All Ages" or younger children.
