This is a new case of 50 - 75 gram cleaning tablets.

Some information from online:

These Alto-Shaam cleaning tabs help keep your Combitherm oven spotless and running efficiently so you can continue to cook meat, vegetables, and more to perfection! They come in 75 gram packets for simple application while removing mixing and measuring from the equation so you don't have to worry about using too little or too much cleaner. 

Best of all, application couldn't be any easier! Simply place the appropriate number of tablets into the oven 's cavity drain and follow the directions outlined in the cleaning instructions.
