Big warning sign on LEGO sets, what's going on?

LEGO enthusiasts in the US have started reporting certain sets bearing very large warning labels regarding button batteries. For LEGO products, button batteries are usually found in light bricks/sound bricks.

Some recent sets with light/sound stones are:

• 21330 Home Alone,
• 76429 Talking Sorting Hat and
• 10300 Back to the Future Time Machine.

After some Google searching, it appears that the appearance of such boxarts now aligns with the labeling date of such products (all button battery products) which should be in effect no later than September 21, 2024, according to this FAQ on the "U.S. Consumer Product Guidance Safety Commission".

This is a direct result of Reese's Law, which was signed by US President Joe Biden in 2022 after it was passed by the US Congress.

Our readers have also noted that the original product images of the current sets have also been resized to allow for the placement of these warning labels without blocking the product image.

The text on these labels must match the size of the primary display panel of any product with coin batteries inside, which explains the huge labels seen on those sets.

These labels won't be going away in the US anytime soon, so we have a feeling that adult box art enthusiasts could source their sets from other regions.
